Overview

The MCP1700T-3002E/TT is a CMOS low dropout (LDO) voltage regulator capable of delivering up to 250mA of current with an extremely low quiescent current of 1.6uA. This specific variant provides a fixed 3.0V output from an input voltage of up to 6V, making it ideal for battery-powered applications where power conservation is critical. It is AEC-Q100 qualified, ensuring reliability in automotive environments and other demanding industrial settings.

Why Choose This Part

The primary advantage is the exceptionally low quiescent current of 1.6uA, which is significantly lower than many competing LDOs. It maintains stability with just a 1.0uF ceramic output capacitor, reducing total PCB footprint and BOM cost. Integrated overcurrent and overtemperature protection, combined with AEC-Q100 qualification, provides a robust power solution in a compact SOT-23 package.

Applications

Battery-Powered Handheld Devices
Extends battery life in portable electronics due to the ultra-low 1.6uA quiescent current when the system is in standby.
Automotive Sensor Clusters
Provides a stable 3.0V rail for sensors and microcontrollers in vehicle subsystems requiring AEC-Q100 qualification.
Remote IoT Nodes
Maintains regulation for wireless modules and low-power MCUs in energy-harvesting or long-term battery deployments.
Point-of-Load Regulation
Local regulation for sensitive analog components that require a stable voltage rail with short circuit and overtemperature protection.

Getting Started

To implement this regulator, place a 1.0uF ceramic capacitor as close as possible to the input and output pins for stability. Ensure the input voltage does not exceed the 6V maximum rating and account for the SOT-23 thermal resistance when operating at the full 250mA load. For prototyping, this part can be used on SOT-23-3 breakout boards for easy integration into breadboard circuits.
