TPS7A4701QRGWRQ1 TI LDO Regulator | 20-VQFN (5x5) | 1A, 1.4V-20V Input

Product Overview

The TPS7A4701QRGWRQ1 from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for automotive and industrial applications. It offers a wide input voltage range from 1.4V to 20V and delivers up to 1A of output current with excellent line and load regulation. The device features an ultra-low noise output (4.4 µVRMS) and high PSRR (55 dB at 1 MHz), making it ideal for noise-sensitive power rails. Housed in a compact 20-VQFN (5x5 mm) package, it is qualified to AEC-Q100 for automotive reliability.
