MCHPMCP1700T-5002E/TT
Overview
The MCP1700T-5002E/TT is a CMOS low dropout (LDO) voltage regulator designed to deliver up to 250mA while consuming an ultra-low quiescent current of only 1.6uA. It provides a fixed 5V output from an input voltage up to 6V, making it an ideal choice for extending battery life in portable applications. The device is housed in a compact SOT-23 package and is AEC-Q100 qualified for automotive reliability.
Why Choose This Part
The primary advantage is the exceptionally low quiescent current of 1.6uA, which is significantly lower than standard LDOs. It requires only a 1uF ceramic output capacitor for stability, reducing the overall PCB footprint and BOM cost. Additionally, integrated short circuit and overtemperature protection enhance system robustness.
Applications
Key Specifications
Getting Started
To use this LDO, place a 1uF ceramic capacitor as close as possible to the input and output pins for stability and transient response. Ensure the input voltage remains between 2.3V and 6V, noting that the 5V output requires sufficient headroom for regulation at higher load currents. No external bypass capacitor is required for the internal reference.
