LP3990TLX-2.8/NOPB TI LDO Regulator | 4-DSBGA(1x1) | 2.8V Fixed Output, 150mA

Product Overview

The LP3990TLX-2.8/NOPB is a low-dropout linear regulator from Texas Instruments, offering a fixed output voltage of 2.8V 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 power-supply rejection ratio (PSRR) and low quiescent current. The device features a typical dropout voltage of 120mV at 150mA load, making it suitable for battery-powered systems. With an input voltage range from 2.5V to 6.0V, it provides a stable output with ±2% accuracy over line, load, and temperature variations.
