  7. LM 317 Power supply • The diodes D2 and D3 in the circuit prevent damage to the regulator during certain adverse conditions such as the output voltage being higher than the input voltage to the regulator or the capacitor across R2 from discharging through the adjustment terminal of the regulator. www.ustudy.in

  12. LM 317 Voltage Regulator calculator • This Voltage Regulator Calculator will work for most voltage regulators with a reference voltage (VREF) of 1.25. • For the LM338 and LM350 regulators, 120 ohms is typically used for R1. • However, other values such as 150 or 220 ohms can also be used for R1. www.ustudy.in

  14. LM 317 Current Regulator calculator • This Current Regulator Calculator will work for adjustable regulators with a reference voltage (VREF) of 1.25. • To determine the output current from the regulator, enter a value for the program resistor (R1) in ohms and press the "Calculate" button. • This will calculate the Output Current in Amperes and the amount of Power Dissipated across R1 in Watts. www.ustudy.in
