TPS7A7401DSDR TI LDO Regulator | 8-WSON (3x3) | 1A, 1.4μVrms Noise

Product Overview

The TPS7A7401DSDR is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver up to 1A of output current with exceptional noise performance and high power supply rejection ratio (PSRR). Housed in a compact 8-WSON (3x3 mm) package, this device is ideal for noise-sensitive applications such as RF, analog, and precision data acquisition systems. With an ultra-low output noise of 1.4 μVrms (10 Hz to 100 kHz) and a PSRR of 40 dB at 1 MHz, the TPS7A7401DSDR ensures clean power delivery to sensitive loads. The device supports an input voltage range from 1.4V to 6.5V and provides an adjustable output voltage from 0.8V to 5.2V with ±1% accuracy over line, load, and temperature.
