LP590745QDQNRQ1 TI LDO Regulator | 4-X2SON(1x1) | 250mA, 1% Accuracy

Product Overview

The LP590745QDQNRQ1 is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive and industrial applications. It delivers up to 250 mA output current with excellent accuracy (1% typical) and low quiescent current. The device is available in a compact 4-pin X2SON package (1 mm x 1 mm), making it ideal for space-constrained designs. With a wide input voltage range of 2.2 V to 5.5 V and an adjustable output voltage from 0.8 V to 4.5 V, it provides flexibility for powering sensitive analog and digital circuits. The LP590745QDQNRQ1 features low noise (30 µVRMS typical), high PSRR (70 dB at 1 kHz), and built-in protection including overcurrent and thermal shutdown.
