Overview

The MCP1700T-2802E/TT is a CMOS low dropout (LDO) voltage regulator that provides a fixed 2.8V output with an extremely low quiescent current of 1.6uA typical. It is designed to deliver up to 250mA of output current while maintaining a low dropout voltage of 0.35V at full load, making it ideal for extending battery life in portable applications.

Why Choose This Part

The primary advantage is the ultra-low 1.6uA quiescent current, which is significantly lower than standard LDOs, minimizing parasitic drain. It also features AEC-Q100 qualification for high-reliability environments and includes integrated short-circuit and overtemperature protection.

Applications

Battery-Powered IoT Nodes
Provides efficient power regulation for sensors and MCUs in long-life wireless nodes where idle power consumption must be minimized.
Automotive Sensor Modules
Utilizes AEC-Q100 qualification to provide stable power to localized sensors within vehicle subsystems.
Smoke and CO2 Detectors
Supports long-term monitoring devices that remain in standby for years on a single battery cell.
Portable Medical Wearables
Offers a small SOT-23 footprint and low heat generation for compact, body-worn health monitoring electronics.

Getting Started

To implement this LDO, place a 1uF ceramic capacitor on both the input and output pins for stability. Ensure the input voltage remains between 2.3V and 6V for a stable 2.8V output. Evaluation can be performed using generic SOT-23 breakout boards or by integrating it directly into a PCB layout following the standard pinout: Ground, Vout, Vin.
