WebFeb 3, 2011 · The LM317T from National Semiconductor is a popular adjustable-voltage regulator that provides output voltages of 1.25 to 37V with maximum 1.5A current. You can adjust the output voltage with a potentiometer. The circuit in Figure 1 replaces the potentiometer with an analog voltage that you can control from a PWM (pulse-width … WebMar 2, 2024 · The LM317 is designed to maintain 1.5V across R1. This is a constant and does not change as long as the input voltage is sufficiently high. Therefore, a voltage across R2 will be developed by the sum of the current: Iadj + 1.5/R1. The output voltage will be 1.5V plus the voltage across R2. – Louis Mar 2 at 1:31

WebDec 17, 2024 · The LM337 is a floating regulator with three terminals. It basically works by generating a precise -1.25 V reference (V ref) between its output and the regulation terminals. This reference voltage is transformed to a programming current (I PROG) by R, as shown in Figure 17. As a result, this constant current travels via R2 from the ground. WebThe LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%.
