Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
Texas Instruments LP38856SX-1-2 is a positive fixed linear voltage regulator with a 1.2V output and a 3A current capability. This device is designed for surface mount applications and is supplied in a TO-263 (DDPAK-5) package. Key features include an enable pin for control, over current, over temperature, short circuit, and under voltage lockout (UVLO) protection. The regulator offers a typical quiescent current of 300 µA. Its high power supply rejection ratio (PSRR) ranges from 80dB to 65dB across 120Hz to 1kHz. The maximum input voltage is 5.5V, and the dropout voltage is 0.45V at 3A. This component finds application in power management for automotive and industrial systems requiring robust voltage regulation.
