TLV77428PDQNR TI Linear Regulator | 4-X2SON (1x1) | 2.8V Output, 150mA

Product Overview

The TLV77428PDQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It delivers a fixed 2.8V output with a maximum output current of 150mA. The device operates over a wide input voltage range from 2.5V to 6V and features ultra-low quiescent current (typical 1.5µA), making it ideal for battery-powered systems. Housed in a compact 4-pin X2SON (1mm x 1mm) package, it offers excellent thermal performance and small footprint.
