TPS7A9401DSCR TI LDO Regulator | 10-WSON (3x3) | 1A, 1.5μVrms Noise

Product Overview

The TPS7A9401DSCR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver up to 1A of output current with exceptional noise performance. Housed in a compact 10-WSON (3x3 mm) package, this device offers an ultra-low output noise of 1.5 μVrms (10 Hz to 100 kHz) and a high power supply rejection ratio (PSRR) of 60 dB at 1 MHz, making it ideal for noise-sensitive applications such as RF, analog, and precision circuits. The input voltage range is from 1.4V to 6.5V, and the output voltage is adjustable from 0.8V to 5.0V with an accuracy of ±1%.
