TPS7A0228PYCHR TI LDO Regulator | 4-DSBGA (0.64X0.64) | 250mA, 1.0V-5.5V

Product Overview

The TPS7A0228PYCHR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for space-constrained applications. It offers a fixed output voltage of 2.8V with a maximum output current of 250mA. Housed in a compact 4-pin DSBGA package (0.64mm x 0.64mm), it is ideal for portable and battery-powered devices where board space is at a premium. The device features ultra-low quiescent current (typical 25nA) and high PSRR, making it suitable for noise-sensitive analog and RF circuits.
