Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LM2941T/LB03

LM2941T/LB03

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

The LM2941T/LB03 is a 1A low dropout adjustable voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 6V to 26V and provides an adjustable output voltage from 5V to 20V. The device features a maximum dropout voltage of 1V at full load, with a typical value of 0.5V. It includes internal thermal overload protection, short-circuit current limiting, and safe area compensation. The component is housed in a TO-220 package with five pins and supports an operating temperature range from -40°C to +125°C.

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

Integrated thermal overload protection and short-circuit current limiting for robust operation under fault conditions
Adjustable output voltage capability allowing flexible design configurations within specified limits
