TPS7A5401RPSR TI LDO Regulator | 12-VQFN-HR (2.2x2.5) | 1A, 500mV Dropout

Product Overview

The TPS7A5401RPSR 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 a dropout voltage as low as 500mV at full load. The device operates over a wide input voltage range from 1.5V to 6.5V and provides an adjustable output voltage from 0.8V to 5.5V. Housed in a compact 12-VQFN-HR (2.2mm x 2.5mm) package, it offers excellent thermal performance and space savings for dense PCB layouts.
