LP38691SD-2.5/NOPB TI LDO Regulator | 6-WSON (3x3) | 2.5V Fixed Output, 500mA

Product Overview

The LP38691SD-2.5/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 2.5V with a maximum output current of 500mA. Housed in a compact 6-WSON (3x3 mm) package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP38691 features a low dropout voltage of typically 250mV at full load, enabling efficient operation even with small input-to-output voltage differentials. It includes built-in protection features such as overcurrent and thermal shutdown, ensuring reliable performance in demanding environments.
