TPS7A3001DRBR TI Linear Regulator | 8-SON(3x3) | -36V, -200mA, Low Noise

Product Overview

The TPS7A3001DRBR from Texas Instruments is a high-performance, low-dropout (LDO) linear regulator designed for negative voltage regulation. It delivers up to -200 mA output current with a wide input voltage range from -3 V to -36 V. The device features ultra-low noise (12 µVRMS) and high PSRR (65 dB at 1 kHz), making it ideal for noise-sensitive applications. Housed in a compact 8-pin SON (3x3 mm) package, it offers excellent thermal performance and space savings.
