Overview

The MCP1703AT-5002E/CBVAO is an AEC-Q100 qualified low dropout (LDO) voltage regulator capable of delivering up to 250mA of current. It features an extremely low quiescent current of 2.0 microamps, making it ideal for battery-powered automotive applications that require a 5.0V rail from an input up to 16V.

Why Choose This Part

The primary benefit is the 2.0 microamp quiescent current, which minimizes battery drain during sleep cycles. It is also automotive AEC-Q100 qualified, ensuring reliability in harsh temperature and vibration environments.

Applications

Automotive Battery Keep-Alive
Provides power to modules that must remain active when the ignition is off, such as keyless entry systems and alarm sensors.
Distributed Power Systems
Acts as a local 5V regulator for sensors and interface ICs in industrial or vehicle bus environments.
Portable Handheld Instruments
Powers logic circuits in battery-operated tools where long standby times are critical.

Getting Started

When designing the PCB, place a 1uF ceramic output capacitor close to the pins to ensure stability across the full load range. Ensure the input voltage does not exceed the 16V maximum rating, particularly during load dump scenarios in automotive circuits.
