LM2941SX/NOPB Description

Short technical summary and product information.

The LM2941SX/NOPB is a positive adjustable linear voltage regulator from Texas Instruments capable of delivering 1A output current. It accepts an input voltage range of 6V to 26V and provides an adjustable output from 5V to 20V. The typical dropout voltage is 0.5V at 1A, with a maximum of 1V. Quiescent current is only 30mA. The regulator offers a power supply rejection ratio (PSRR) of 67dB at 100kHz and output noise of 600µVrms. Operating temperature range is -40°C to 125°C. Protection features include over temperature, reverse polarity, and short circuit. The device includes an enable control pin. Output accuracy is 5%. A minimum load capacitance of 22µF is required. The regulator is available in a surface mount DDPAK/TO-263-5 package, also referenced as TO-263-6 or D²Pak (5 Leads + Tab).
