Overview

The MCP1700T-5002E/MB is a CMOS low dropout (LDO) voltage regulator that provides a fixed 5.0V output with an exceptionally low quiescent current of 1.6uA. It supports an input voltage up to 6V and can deliver up to 250mA of output current, making it ideal for battery-operated systems where minimizing standby power consumption is critical.

Why Choose This Part

The primary advantage is the ultra-low 1.6uA quiescent current, which is significantly lower than standard bipolar LDOs. It also features AEC-Q100 qualification for automotive reliability and includes integrated short circuit and overtemperature protection within a compact SOT-89 footprint.

Applications

Battery-Powered Smoke and CO Detectors
Extends battery life in safety sensors by maintaining a tiny 1.6uA quiescent current during long monitoring periods.
Smart Battery Packs
Provides a stable 5V rail for fuel gauge ICs and protection circuitry with minimal thermal overhead in SOT-89 packaging.
Handheld Portable Devices
Supplies regulated power to microcontrollers and peripherals in PDAs and pagers while surviving input transients up to 6V.
Automotive Sensor Modules
Utilizes AEC-Q100 qualification and overtemperature protection to provide reliable power in vehicle environmental monitoring.

Getting Started

When designing with this LDO, ensure a minimum of 1uF ceramic, tantalum, or aluminum electrolytic capacitance is used on the output for stability. The SOT-89 package provides better thermal dissipation than SOT-23 variants, but designers should still calculate the power dissipation (Vin - Vout) * Iout to ensure the 125C junction temperature is not exceeded.
