Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LM317TG

LM317TG

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

The LM317TG is a monolithic integrated circuit from onsemi, functioning as an adjustable three-terminal positive voltage regulator. It operates within the TO-220 package (Case 221AB) and supports an output voltage range of 1.2 V to 37 V. The device supplies in excess of 1.5 A of load current. Key electrical characteristics include a line regulation of 0.04 %/V and a load regulation of 0.5 %. It features internal thermal overload protection, short-circuit current limiting, and safe-area compensation. The operating junction temperature range extends from -55°C to +150°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Provides adjustable positive output voltage across a wide range using only two external resistors.
Includes comprehensive internal protections such as thermal shutdown, constant current limiting, and safe area compensation.
Supports floating operation for high-voltage applications relative to ground.
