TPS7A4401DGQR TI LDO Regulator | 10-HVSSOP | 500mA, 1.5μVrms Noise

Product Overview

The TPS7A4401DGQR is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a continuous output current of 500 mA with exceptional noise performance. Housed in a compact 10-pin HVSSOP package, this device offers an ultra-low output noise of 1.5 μVrms (10 Hz to 100 kHz) and a high power supply rejection ratio (PSRR) of 60 dB at 1 MHz, making it ideal for noise-sensitive applications. The input voltage range spans from 1.4 V to 6.5 V, and the output voltage is adjustable from 0.8 V to 5.5 V via external resistors. With a dropout voltage of typically 200 mV at full load, the TPS7A4401DGQR ensures efficient operation even under low headroom conditions. It features built-in protection circuits including overcurrent and overtemperature shutdown, as well as a power-good output for system monitoring.
