WebAug 15, 2024 · LM317 adjustable regulator, datasheet specifications: The LM317 is an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 Volts. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. WebThe load resistor acts as a preload on the power supply. It causes a voltage drop. When equipment is attached to the supply, the added drop is fairly small and the regulation is improved. Voltage Regulation Example 2. …
