Lm317 max voltage

LM317 has no max input because there is no ground connected directly to the regulator, there is only a max allowed IN/OUT voltage difference which is 40v, if you can keep restriction and the voltage difference doesn't go over that then the regulator will be fine The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulators.

What are the maximum input current and voltage for an LM317

  1. The LM317 is an adjustable linear voltage regulator. It can take an input voltage of 3-40 Volts DC and outputs a fixed voltage from 1.2 to 37 Volts DC. The output is controlled by resistors on the adjustment pin. Here is a handy calculator to calculate the resistance needed to obtain the desired output voltage
  2. circuit, it can be used at high voltages as long as the input-output differential is within max ratings. But practical loads will place a capacitance at the output of the LM317, with many having a physical capacitor. That capacitance will momentarily short the output to ground at switch-on, causing the LM317's max voltage rating to be exceeded.
