LP3990TL-0.8/NOPB TI LDO Regulator | 4-DSBGA (1x1) | 0.8V Fixed Output, 150mA

Product Overview

The LP3990TL-0.8/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 0.8V with a maximum output current of 150mA. Housed in a compact 4-DSBGA (1x1 mm) package, it is designed for space-constrained applications requiring high performance and low noise. The device features a low dropout voltage of typically 120mV at full load, excellent line and load transient response, and a low quiescent current of 25µA. It also includes enable logic, overcurrent protection, and thermal shutdown, making it a robust solution for powering sensitive analog and digital circuits.
