TPS7A5401QRGRRQ1 TI LDO Regulator | 20-VQFN (3.5x3.5) | 500mA, 1.5μVrms Noise

Product Overview

The TPS7A5401QRGRRQ1 from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for automotive and industrial applications. It offers an output current of 500 mA with an ultra-low noise of 1.5 μVrms (10 Hz to 100 kHz) and high PSRR of 40 dB at 1 MHz. The device operates over a wide input voltage range from 1.5 V to 6.5 V and provides an adjustable output voltage from 0.8 V to 5.5 V. Housed in a compact 20-pin VQFN package (3.5 mm x 3.5 mm), it is qualified to AEC-Q100 for automotive reliability.
