TPS7N4901PDSQR TI LDO Regulator | 10-WSON (2x2) | 1A, 0.8V to 5.5V

Product Overview

The TPS7N4901PDSQR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It offers a wide input voltage range of 0.8V to 5.5V and delivers up to 1A of output current with excellent transient response. The device features ultra-low output noise (4.4 µVRMS) and high PSRR (70 dB at 1 kHz), making it ideal for powering RF, analog, and precision digital circuits. Housed in a compact 10-WSON (2x2 mm) package, it is suitable for space-constrained designs.
