LM317 Variable Voltage Regulator Circuit Whenever we need a constant and specific value of voltage without fluctuation we use voltage regulator IC. They provide a fixed regulated power supply. We have 78XX (7805, 7806, 7812 etc) series voltage regulators for positive power supply and 79XX for ...
The output voltage (ideally) of the LM317 voltage regulator circuit Vout = Vref * (1+ (RL/RH)) An error term is added because some quiescent current flows from the adjustment pin of the device. Vout = Vref * (1+(RL/RH)) + IQR ...
The LM317 / LM338 / LM350 series of voltage regulators can also be configured to regulate current in a circuit. For information about current regulation with these integrated circuit (IC) regulators see the LM317 / LM338 / LM350 Current Regulator Calculator. ...
