Copper Length LM1117 APPLICATIONS INFORMATION Introduction Frequency compensation for the regulator is provided by capacitor Cout and its use is mandatory to ensure output stability. A minimum capacitance value of 4.7 mF with an equivalent series resistance (ESR) that is within the limits of 33 mW (typ) to 2.2 W is required. See Figures 12 and 13. The capacitor type can be ceramic, tantalum, or aluminum electrolytic as long as it meets the minimum capacitance value and ESR limits over the circuit's entire operating temperature range. Higher values of output capacitance can be used to enhance loop stability and transient response with the additional benefit of reducing output noise. The LM1117 features a significant reduction in dropout voltage along with enhanced output voltage accuracy and temperature stability when compared to older industry standard three-terminal adjustable regulators. These devices contain output current limiting, safe operating area compensation and thermal shutdown protection making them designer friendly for powering numerous consumer and industrial products. The LM1117 series is pin compatible with the older LM317 and its derivative device types. Output Voltage Input The typical application circuits for the fixed and adjustable output regulators are shown in Figures 23 and 24. The adjustable devices are floating voltage regulators. They develop and maintain the nominal 1.25 V reference voltage between the output and adjust pins. The reference voltage is programmed to a constant current source by resistor R1, and this current flows through R2 to ground to set the output voltage. The programmed current level is usually selected to be greater than the specified 5.0 mA minimum that is required for regulation. Since the adjust pin current, Iadj, is significantly lower and constant with respect to the programmed load current, it generates a small output voltage error that can usually be ignored. For the fixed output devices R1 and R2 are included within the device and the ground current Ignd, ranges from 3.0 mA to 5.0 mA depending upon the output voltage. Cin Cin + LM1117 XTXX 1 + + + Cout Cadj Vout + Vref 1 ) R2 ) Iadj R2 R1 Figure 24. Adjustable Output Regulator The output ripple will increase linearly for fixed and adjustable devices as the ratio of output voltage to the reference voltage increases. For example, with a 12 V regulator, the output ripple will increase by 12 V/1.25 V or 9.6 and the ripple rejection will decrease by 20 log of this ratio or 19.6 dB. The loss of ripple rejection can be restored to the values shown with the addition of bypass capacitor Cadj, shown in Figure 24. The reactance of Cadj at the ripple frequency must be less than the resistance of R1. The value of R1 can be selected to provide the minimum required load current to maintain regulation and is usually in the range of 100 W to 200 W. Cadj u 1 2 p fripple R1 The minimum required capacitance can be calculated from the above formula. When using the device in an application that is powered from the AC line via a transformer and a full wave bridge, the value for Cadj is: Output 2 R1 Vref 1 Output 2 R2 Input bypass capacitor Cin may be required for regulator stability if the device is located more than a few inches from the power source. This capacitor will reduce the circuit's sensitivity when powered from a complex source impedance and significantly enhance the output transient response. The input bypass capacitor should be mounted with the shortest possible track length directly across the regulator's input and ground terminals. A 10 mF ceramic or tantalum capacitor should be adequate for most applications. 3 + LM1117 XTA Iadj External Capacitors Input 3 fripple + 120 Hz, R1 + 120 W, then Cadj u 11.1 mF The value for Cadj is significantly reduced in applications where the input ripple frequency is high. If used as a post regulator in a switching converter under the following conditions: Cout Ignd fripple + 50 kHz, R1 + 120 W, then Cadj u 0.027 mF Figure 23. Fixed Output Regulator Figures 10 and 11 shows the level of ripple rejection that is obtainable with the adjust pin properly bypassed. www.onsemi.com 8 LM1117 Protection Diodes The second condition is that the ground end of R2 should be connected directly to the load. This allows true Kelvin sensing where the regulator compensates for the voltage drop caused by wiring resistance RW -. The LM1117 family has two internal low impedance diode paths that normally do not require protection when used in the typical regulator applications. The first path connects between Vout and Vin, and it can withstand a peak surge current of about 15 A. Normal cycling of Vin cannot generate a current surge of this magnitude. Only when Vin is shorted or crowbarred to ground and Cout is greater than 50 mF, it becomes possible for device damage to occur. Under these conditions, diode D1 is required to protect the device. The second path connects between Cadj and Vout, and it can withstand a peak surge current of about 150 mA. Protection diode D2 is required if the output is shorted or crowbarred to ground and Cadj is greater than 1.0 mF. Input Cin Cin + RW+ 2 + R1 1 Cout R2 Output Remote Load Figure 26. Load Sensing Thermal Considerations 1N4001 3 + LM1117 XTA RW- D1 Input 3 LM1117 XTA 1 R2 This series contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 175C, the regulator output switches off and then back on as the die cools. As a result, if the device is continuously operated in an overheated condition, the output will appear to be oscillating. This feature provides protection from a catastrophic device failure due to accidental overheating. It is not intended to be used as a substitute for proper heatsinking. The maximum device power dissipation can be calculated by: Output 2 R1 + D2 1N4001 + Cout Cadj Figure 25. Protection Diode Placement A combination of protection diodes D1 and D2 may be required in the event that Vin is shorted to ground and Cadj is greater than 50 mF. The peak current capability stated for the internal diodes are for a time of 100 ms with a junction temperature of 25C. These values may vary and are to be used as a general guide. PD + TJ(max) * TA RqJA The devices are available in surface mount SOT-223 and DPAK packages. Each package has an exposed metal tab that is specifically designed to reduce the junction to air thermal resistance, RqJA, by utilizing the printed circuit board copper as a heat dissipater. Figures 21 and 22 show typical RqJA values that can be obtained from a square pattern using economical single sided 2.0 ounce copper board material. The final product thermal limits should be tested and quantified in order to insure acceptable performance and reliability. The actual RqJA can vary considerably from the graphs shown. This will be due to any changes made in the copper aspect ratio of the final layout, adjacent heat sources, and air flow. Load Regulation The LM1117 series is capable of providing excellent load regulation; but since these are three terminal devices, only partial remote load sensing is possible. There are two conditions that must be met to achieve the maximum available load regulation performance. The first is that the top side of programming resistor R1 should be connected as close to the regulator case as practicable. This will minimize the voltage drop caused by wiring resistance RW + from appearing in series with reference voltage that is across R1. www.onsemi.com 9 LM1117 Input LM1117 XTA 3 + 10 mF Constant Current Output R 2 + 1 Input + 10 mF 10 mF LM1117 XTA 3 Output 2 + R1 1 R2 50 k 2N2907 Figure 28.
