TPS7A5301RPSR TI LDO Regulator | 12-VQFN-HR (2.2x2.5) | 1A, 1.5μVrms Noise

Product Overview

The TPS7A5301RPSR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver up to 1A of output current with exceptional noise performance and power supply rejection ratio (PSRR). Housed in a compact 12-pin VQFN-HR package (2.2mm x 2.5mm), this device is ideal for space-constrained applications requiring clean power rails. With an ultra-low output noise of 1.5μVrms (10Hz to 100kHz) and a PSRR of 60dB at 1MHz, the TPS7A5301RPSR ensures minimal ripple and noise coupling into sensitive loads. The input voltage range spans from 1.4V to 6.5V, and the output voltage is adjustable from 0.8V to 5.5V via external resistors. Additional features include enable control, soft-start, overcurrent protection, and thermal shutdown.
