Overview

The LD59150PURY is an AEC-Q100 qualified, 1.5A high-accuracy linear voltage regulator designed for automotive and industrial applications. It features a wide input range from 0.8V to 5.5V and maintains a low typical noise floor of 25nV/sqrt(Hz) for sensitive electronic loads.

Why Choose This Part

This regulator offers high precision with 0.5% output voltage accuracy and high reliability via AEC-Q100 qualification and wettable flank packaging for improved solder joint inspection. It includes integrated Power Good and programmable soft-start features to manage complex system power sequencing.

Applications

Automotive ADAS Systems
Provides clean power to radar and camera sensors that require high PSRR and low noise performance.
MCU and FPGA Core Rails
Supplies high-current, low-voltage rails for digital processing cores with 0.5% accuracy.
Infotainment Systems
Powers noise-sensitive audio and display circuitry in vehicle head units.

Getting Started

When designing the PCB, place a low-ESR ceramic capacitor of at least 2.2 microfarads close to the output pin for stability. Use the EN pin for power sequencing and monitor the PGOOD pin to signal the downstream processor when the 0.8V to 3.6V output has reached regulation.
