About this product
The LM317T is a three-terminal adjustable positive linear voltage regulator in a TO-220 package. It provides an output from 1.2V to 37V at up to 1.5A and needs only two external resistors to set the output voltage. It is commonly used to build regulated supply rails and bench-style power circuits for hobby and student projects.

How do I set the output voltage of the LM317T?
Connect a resistor R1 (commonly 240 ohm) between OUT and ADJ, and a variable resistor R2 between ADJ and GND. The output is approximately Vout = 1.25V x (1 + R2/R1), plus a small adjust-pin current term. Adjust R2 to reach the target voltage.
What input voltage does the LM317T need?
The input must be higher than the output by the regulator's dropout voltage, typically around 2V to 3V, to keep regulation. Use a heat sink when the input-output difference and current are high, because the excess power is dissipated as heat.
