LM117/LM317 Adjustable Voltage Regulators

The Texas Instruments LM117/LM317 series of adjustable three-terminal positive voltage regulators are available with current ratings of 0.1, 0.5 and 1.5A. Output voltage range is from 1.25 V to 37 V and is set by two external resistors. These robust and reliable devices incorporate current limiting, thermal overload protection, and safe operating area protection.

Output Voltage Range: 1.2 V to 37 V
Output Current: 1.5 A (LM317), 0.5 A (LM317M), 0.1 A (LM317L)
Typical line regulation: 0.01%
Typical load regulation: 0.1%

This linear regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. The current limit is constant with temperature, it also features short circuit protection output.
