Product Overview
The LP38843S-1.2/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 1.2V with a maximum output current of 3A. Housed in a TO-263 (DDPAK-5) package, this device is designed for applications requiring high efficiency and low noise. The LP38843S-1.2/NOPB features a low dropout voltage of typically 120mV at full load, enabling operation with minimal input-to-output voltage differential. It also includes enable/shutdown functionality, overcurrent protection, and thermal shutdown for robust system design.
