TPS7A5301RPST TI LDO Regulator | 12-VQFN-HR (2.2x2.5) | 1A, 1.5μVrms Noise

Product Overview

The TPS7A5301RPST from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver up to 1A of continuous output current with exceptional low noise and high 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 input voltage range from 1.4V to 6.5V and an adjustable output voltage down to 0.8V, the TPS7A5301RPST offers flexibility for various low-voltage designs. Its ultra-low output noise of 1.5μVrms (10Hz to 100kHz) and high PSRR of 60dB at 1MHz make it suitable for noise-sensitive circuits such as RF, analog, and precision instrumentation.
