LP38691DTX-1.8/NOPB TI LDO Regulator | TO-252-3 | 1.8V Fixed Output, 500mA

Product Overview

The LP38691DTX-1.8/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.8V with a maximum output current of 500mA. Housed in a TO-252-3 (DPAK) package, this device is designed for space-constrained applications requiring high accuracy and low noise. With a dropout voltage of typically 250mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP38691DTX-1.8/NOPB features a wide input voltage range from 2.7V to 10V, making it suitable for various power supply designs. Its low quiescent current of 55µA (typical) enhances battery life in portable devices. The device includes built-in current limit and thermal shutdown protection, ensuring reliable operation under fault conditions.
