Texas Instruments LP38855S-1-2 is a 1.2V positive fixed output linear voltage regulator. This component delivers 1.5A of output current with a low dropout voltage of 0.18V at 1.5A. The device features an enable pin for control and includes comprehensive protection against over current, over temperature, short circuit, and under voltage lockout (UVLO). With a quiescent current of 300 µA and an input voltage range up to 5.5V, it is suitable for applications demanding efficient power management. The LP38855S-1-2 offers excellent power supply rejection ratio (PSRR) performance, ranging from 80dB to 65dB across a 120Hz to 1kHz frequency spectrum. It is supplied in a TO-263 (DDPAK-5) surface-mount package and operates across a temperature range of -40°C to 125°C. This regulator finds application in various industries, including automotive and industrial systems.
