TPS7A5301BRPSR TI LDO Regulator | 12-VQFN-HR (2.2x2.5) | 1A, 1.5μVrms Noise

Product Overview

The TPS7A5301BRPSR is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments. It offers an ultra-low noise output of 1.5 μVrms (10 Hz to 100 kHz) and high power supply rejection ratio (PSRR) of 45 dB at 1 MHz, making it ideal for noise-sensitive applications. With a maximum output current of 1 A and a dropout voltage of typically 120 mV at full load, this regulator provides excellent efficiency and stability. The device operates over an input voltage range of 1.4 V to 6.5 V and delivers an adjustable output voltage from 0.8 V to 5.5 V. Housed in a compact 12-pin VQFN-HR package (2.2 mm x 2.5 mm), it is suitable for space-constrained designs.
