LM317C

The LM317C is a three terminal positive voltage regulator with adjustable output. By setting two peripheral resistors, the output voltage range of the device can be set from 1.25V to 37V, and the current up to 1.5A can be provided. The LM317C integrates current limiting, thermal overload protection and safe operation area protection internally, and corresponding capacitors can be added to improve transient response. Therefore, the device is very easy to use, which is difficult to achieve with a standard three terminal regulator.
