Texas Instruments LP38855SX-1-2 is a fixed output voltage linear regulator providing 1.2V and capable of delivering up to 1.5A. This positive voltage regulator features a low dropout of 0.18V at 1.5A, ensuring efficient operation with minimal voltage headroom. The device offers robust protection mechanisms including over current, over temperature, short circuit, and under voltage lockout (UVLO). With a typical quiescent current of 300 µA and a low supply current of 15 mA (max), it is suitable for power-sensitive applications. The regulator boasts a high power supply rejection ratio (PSRR) ranging from 80dB to 65dB across a frequency range of 120Hz to 1kHz. Its TO-263-6, D2PAK (5 leads + tab) surface mount package facilitates integration into compact designs. The LP38855SX-1-2 is designed for operation across an industrial temperature range of -40°C to 125°C and is supplied on tape and reel. Applications include power supplies for communication infrastructure, automotive systems, and industrial control.
