TPS7A9001DSKR TI LDO Regulator | 10-SON (2.5x2.5) | 1A, 1.4μVrms Noise, 0.5% Accuracy

Product Overview

The TPS7A9001DSKR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It delivers up to 1A of output current with an ultra-low output noise of 1.4 μVrms (10 Hz to 100 kHz) and high PSRR of 45 dB at 1 MHz. The device operates over a wide input voltage range of 1.4V to 6.5V and provides an adjustable output voltage from 0.8V to 5.5V. Housed in a compact 10-pin SON package (2.5 mm × 2.5 mm), it is ideal for space-constrained designs requiring clean power rails.
