LP590729QDQNRQ1 TI LDO Regulator | 4-X2SON(1x1) | 250mA, 1.2V Output

Product Overview

The LP590729QDQNRQ1 is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive and industrial applications. It delivers up to 250mA output current with a fixed output voltage of 1.2V. Housed in a compact 4-pin X2SON (1mm x 1mm) package, it offers excellent line and load regulation, low noise, and high PSRR, making it ideal for noise-sensitive power rails in advanced driver-assistance systems (ADAS), infotainment, and telematics.
