Datasheet 500-mA 3.3-V or 5.0-V Output LDO Regulators BD4xxM5-C Series General Description Features The BD4xxM5 series are low quiescent regulators featuring 45 V absolute maximum voltage, and output voltage accuracy of 2 % (3.3 V or 5 V: Typ.), 500 mA output current and 38 A (Typ.) current consumption. These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption. A logical "HIGH" at the CTL enables the device and "LOW" at the CTL disables the device. (Only W: Includes Enable Input). Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, these ICs also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions. Qualified for Automotive Applications Wide Temperature Range (Tj): -40 C to +150 C Wide Operating Input Range: 3.0 V to 42 V Low Quiescent Current: 38 A (Typ.)

Choose the capacitance according to the line between the power smoothing circuit and the VCC. Selection of the capacitance also depends on the application. Verify the application and allow sufficient margins in the design. We recommend using a capacitor with excellent voltage and temperature characteristics. Output Pin Capacitor In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND. We recommend using a capacitor with a capacitance of 10 F (Typ.) or higher. Electrolytic, tantalum and ceramic capacitors can be used. When selecting the capacitor ensure that the capacitance of 6 F or higher is maintained at the intended applied voltage and temperature range. Due to changes in temperature the capacitor's capacitance can fluctuate possibly resulting in oscillation. For selection of the capacitor refer to the data of Figure 41. The stable operation range given in the data of Figure 41 and Figure 42 is based on the standalone IC and resistive load. For actual applications the stable operating range is influenced by the PCB impedance, input supply impedance and load impedance. Therefore verification of the final operating environment is needed. When selecting a ceramic type capacitor, we recommend using X5R, X7R or better with excellent temperature and DC-biasing characteristics and high voltage tolerance. Also, in case of rapidly fluctuation of input voltage and load current, select the capacitance in accordance with verifying that the actual application meets with the required specification. Mount the capacitor as much as possible near connected pin.

Within this IC, the power consumption is decided by the dropout voltage condition, the load current and the circuit current. Refer to power dissipation curves illustrated in Figure 44, 45 when using the IC in an environment of Ta 25 C. Even if the ambient temperature Ta is at 25 C, depending on the input voltage and the load current, chip junction temperature can be very high. Consider the design to be Tj Tjmax = 150 in all possible operating temperature range. Should by any condition the maximum junction temperature Tjmax = 150 rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient margins in the thermal design by the following method is used to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods. 1. The following method is used to calculate the junction temperature Tj.

In this event it also becomes impossible to determine the cause of the damage (e.g. short circuit, open circuit, etc.). Therefore, if any special mode is being considered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered. 2) The electrical characteristics given in this specification may be influenced by conditions such as temperature, supply voltage and external components. Transient characteristics should be sufficiently verified. 3) GND Electric Potential Keep the GND potential at the lowest (minimum) level under any operating condition. Furthermore, ensure that, including the transient, none of the pin's voltage is less than the GND voltage. 4) GND Wiring Pattern When both a small-signal GND and a high current GND are present, single-point grounding (at the set standard point) is recommended. This in order to separate the small-signal and high current patterns and to ensure that voltage changes stemming from the wiring resistance and high current do not cause any voltage change in the small-signal GND. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. 5) CTL Do not make voltage level of chip enable keep floating level, or in between VthH and VthL. Otherwise, the output voltage would be unstable or indefinite. 6) Inter-pin Shorting and Mounting Errors Ensure that when mounting the IC on the PCB the direction and position are correct. Incorrect mounting may result in damaging the IC. Also, shorts caused by dust entering between the output, input and the GND may result in damaging the IC. 7) Inspection Using the Set Board The IC needs to be discharged after each inspection process as, while using the set board for inspection, connecting a capacitor to a low-impedance pin may cause stress to the IC. As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with transportation and storage. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment. 8) Thermal Design The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin should be allowed for in the thermal design. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible. The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. Should by any condition the maximum junction temperature Tjmax = 150 rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient margins in the thermal design. 9) Overcurrent Protection Circuit This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. 10) Thermal Shut Down (TSD) This IC incorporates and integrated thermal shutdown circuit to prevent heat damage to the IC. Normal operation should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature (Tj) will rise and the TSD circuit will be activated and turn all output pins OFF. After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. www.rohm.com (c) 2015 ROHM Co., Ltd.

For example, the accumulated charge in the output pin capacitor flowing backward from the VOUT to the VCC when the VCC shorts to the GND. In order to minimize the damage in such case, use a capacitor with a capacitance less than 1000 F. Also by inserting a reverse polarity diode in series to the VCC, it can prevent reverse current from reverse battery connection or the case. When the point A is short-circuited GND, if there may be any possible case point B is short-circuited to GND, we also recommend using a bypass diode between the VCC and the VOUT. Bypass Diode Reverse Polarity Diode A VCC B VO GND Figure 50. Recommend Example of Using Diodes 12) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P/N junctions are formed at the intersection of these P layers with the N layers of other elements to create a variety of parasitic elements. For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: The P/N junction functions as a parasitic diode when the GND > pin A for the resistor, or the GND > pin B for the transistor. Also, when the GND > pin B for the transistor (NPN), the parasitic diode described above combines with the N layer of the other adjacent elements to operate as a parasitic NPN transistor. Parasitic diodes inevitably occur in the structure of the IC. Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip. Therefore do not employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the (P substrate) GND. Figure 51.
