The equivalent series resistance (ESR) of the output capacitor must be in the stable operation area. However, it is recommended to use as large a value of capacitance as is practical. The output noise and the ripple noise decrease as the capacitance value increases. ESR values vary widely between ceramic and tantalum capacitors. However, tantalum capacitors are assumed to provide more ESR damping resistance, which provides greater circuit stability. This implies that a higher level of circuit stability can be obtained by using tantalum capacitors when compared to ceramic capacitors with similar values. For output voltage device 2.0V applications, the recommended value of CL0.10F. For output voltage device 1.5V applications, the recommended value of CL0.22F 014011331-E-00 - 11 - 2014/10 [AP1150ADSXX] The input capacitor is necessary when the battery is discharged, the power supply impedance increases, or the line distance to the power supply is long. This capacitor might be necessary on each individual IC even if two or more regulator ICs are used. It is not possible to determine this indiscriminately. Please confirm the stability while mounted. The IC provides stable operation with an output side capacitor of 0.1F (Vout2.0V). If it is 0.1F or more over the full range of temperature, either a ceramic capacitor or tantalum capacitor can be used without considering ESR. CIN=0.22 to 0.1F CL=0.22 to 0.1F CNP=0.01F Figure 2.

A design with little electric power loss can be implemented. We recommend the use of the on/off control of the regulator without using a high side switch to provide an output from the regulator. A highly accurate output voltage with low voltage drop is obtained. Because the Vcont terminal current is small, it is possible to control it directly by CMOS logic. Vsat REG On/Off Cont. Figure 4. Equivalent circuit of output 11.5 Noise Bypass The noise and the ripple rejection characteristics depend on the capacitance on the Np terminal. The ripple rejection characteristic of the low frequency region improves by increasing the capacitance of Cnp. A standard value is Cnp=0.001F. Increase Cnp in a design with important output noise and ripple rejection requirements. The IC will not be damaged if the capacitor value is increased. The on/off switching speed changes depending on the Np terminal capacitance. The switching speed slows when the capacitance is large. 014011331-E-00 - 13 - 2014/10 [AP1150ADSXX] 11.6 Board Layout Vout VIN on/off Np Figure 5.

Thermal resistance (ja) is=250C/W. The package loss is limited at the temperature that the internal temperature sensor works (about 150C). Therefore, the package loss is assumed to be an internal limitation. There is no heat radiation characteristic of the package unit assumed because of the small size. The device being mounted on the PCB carries heat away. This value changes by the material and the copper pattern etc. of the PCB. The losses are approximately 500mW. Enduring these losses becomes possible in a lot of applications operating at 25C. The overheating protection circuit operates when there are a lot of losses with the regulator (When outside temperature is high or heat radiation is bad). The output current cannot be pulled enough and the output voltage will drop when the protection circuit operates. When the junction temperature reaches 150C, the IC is shut down. However, operation begins at once when the IC stops operation and the temperature of the chip decreases. How to determine the thermal resistance when mounted on PCB The thermal resistance when mounted is expressed as follows: Tj=jaPd+Ta Tj of IC is set around 150C. Pd is the value when the thermal sensor is activated. If the ambient temperature is 25C, then: 150=jaPd+25 ja=125/Pd (C /mW) 014011331-E-00 - 14 - 2014/10 [AP1150ADSXX] The simple method to calculate Pd Mount the IC on the print circuit board. Short between the output terminal and ground. after that, raise input voltage from 0V to evaluated voltage gradually. At shorted the output terminal, the power dissipation PD can be expressed as Pd=VIN Iin. The input current decreases gradually as the temperature of the chip becomes high. After a while, it reaches the thermal equilibrium. Use this currrent value at the thermal equilibrium. In almost all the cases, it shows 500mW or more. In the case that the power, VIN Short Circuit Current, becomes more than twice of the maximum rating of its power dissipation in a moment, there is a possibility that the IC is destroyed before internal thermal protection works. Pd(mW) 2 Pd D Pd 5 4 0 25 50 75 Ta () Procedure (When mounted on PCB.) 1. Find Pd (VINIin when the output side is short-circuited). 2. Plot Pd against 25C. 3. Connect Pd to the point corresponding to the 150C with a straight line. 4. In design, take a vertical line from the maximum 3 operating temperature (e.g., 75C) to the derating curve. 5. Read off the value of Pd against the point at which the vertical line intersects the derating curve. This is taken 100 150 as the maximum power dissipation DPd. 6. DPd (VINmaxVout)=Iout (at 75C) Figure 7. Determine Pd The maximum output current at the highest operating temperature will be Iout DPd (VINMaxVout). Please use the device at low temperature with better radiation. The lower temperature provides better quality. 014011331-E-00 - 15 - 2014/10 [AP1150ADSXX] 12. Definition of term Output Voltage (Vout) The output voltage is specified with VIN=Vout(typ)+1V , and Iout=5mA. Maximum Output Current (IoutMAX) The rated output current is specified under the condition where the output voltage drops 0.3V the value specified with Iout=5mA. The input voltage is set to Vout(typ)+1V and the current is pulsed to minimize temperature effect. Dropout Voltage (Vdrop) The dropout voltage is the difference between the input voltage and the output voltage at which point the regulator starts to fall out of regulation. Below this value, the output voltage will fall as the input voltage is reduced. It is dependent upon the load current and the junction temperature. Line Regulation (LinReg) Line regulation is the ability of the regulator to maintain a constant output voltage as the input voltage changes. The line regulation is specified as the input voltage is changed from VIN=Vout(typ)+1V to VIN= Vout(typ)+6V. It is a pulse measurement to minimize temperature effect. Load Regulation (LoaReg) Load regulation is the ability of the regulator to maintain a constant output voltage as the load current changes. It is a pulsed measurement to minimize temperature effects with the input voltage set to VIN=Vout(typ)+1V. The load regulation is specified output current step conditions of 5mA to 100mA. Ripple Rejection (R.R) Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output. It is specified with 200mVrms, 1kHz super-imposed on the input voltage, where VIN=Vout+1.5V. Ripple rejection is the ratio of the ripple content of the output vs. input and is expressed in dB. Standby Current (Istandby) Standby current is the current, which flows into the regulator when the output is turned off by the control function (Vcont=0V). Over Current Sensor The over current sensor protects the device when there is excessive output current. It also protects the device if the output is accidentally connected to ground. Thermal Sensor The thermal sensor protects the device in case the junction temperature exceeds the safe value (TJ=150C). This temperature rise can be caused by external heat, excessive power dissipation caused by large input to output voltage drops, or excessive output current. The regulator will shut off when the temperature exceeds the safe value. As the junction temperatures decrease, the regulator will begin to operate again. Under sustained fault conditions, the regulator output will oscillate as the device turns off then resets. Damage may occur to the device under extreme fault. Please reduce the loss of the regulator when this protection operate, by reducing the input voltage or make better heat efficiency.In the case that the power, VIN Ishort(Short Circuit Current), becomes more than twice of the maximum rating of its power dissipation in a moment, there is a possibility that the IC is destroyed before internal thermal protection works. Reverse Voltage Protection Reverse voltage protection prevents damage due to the output voltage being higher than the input voltage. This fault condition can occur when the output capacitor remains charged and the input is reduced to zero, or when an external voltage higher than the input voltage is applied to the output side VIN Vout GND 014011331-E-00 - 16 - 2014/10 [AP1150ADSXX] 13.
