LP38691SD-5.0/NOPB TI LDO Regulator | 6-WSON(3x3) | 5V Fixed Output, 500mA

Product Overview

The LP38691SD-5.0/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed 5V output with a maximum output current of 500mA. Housed in a compact 6-WSON (3x3 mm) package, it is designed for space-constrained applications requiring low noise and high PSRR. The device features a low dropout voltage of typically 250mV at full load, enabling efficient operation even with small input-to-output voltage differentials. With an enable pin for power sequencing and thermal shutdown protection, the LP38691SD-5.0/NOPB is ideal for powering sensitive analog and digital circuits in industrial, automotive, and telecommunications systems.
