TPS7A8901RTJT TI LDO Regulator | 20-QFN (4x4) | 1A, 1.5μVrms Noise

Product Overview

The TPS7A8901RTJT from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver up to 1A of output current with exceptional low noise and high power supply rejection ratio (PSRR). Housed in a compact 20-pin QFN package (4mm x 4mm), this device is ideal for noise-sensitive applications such as RF, analog, and precision data acquisition systems. With an output voltage range from 0.8V to 5.2V and an ultra-low output noise of 1.5μVrms (10Hz to 100kHz), the TPS7A8901RTJT ensures clean power delivery for critical loads.
