LM317L

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TAEJIN LM317L is a monolithic integrated circuit functioning as an adjustable three-terminal positive voltage regulator. It provides an output current exceeding 100mA with an adjustable output voltage range spanning from 1.2V to 37V. The device incorporates internal thermal overload protection, short-circuit current limiting, and output transistor safe-area compensation. Recommended operating ratings specify a line regulation of 0.04%/V and load regulation of 25mV at 25°C for outputs up to 5V. The reference voltage is typically 1.25V, with an adjustable pin current of 100µA maximum.
