MCHPMCP1825T-3302E/DCVAO
Overview
The MCP1825T-3302E/DCVAO is a 500mA low dropout (LDO) linear regulator providing a fixed 3.3V output from an input range of 2.1V to 6.0V. This automotive-qualified AEC-Q100 device is designed for high-current applications requiring low quiescent current and stable operation with ceramic output capacitors.
Why Choose This Part
This regulator features an extremely low shutdown current of 0.1uA and a quiescent current of 120uA, maximizing efficiency in battery-powered systems. It includes an Power Good output and Enable pin for sophisticated power sequencing, while maintaining AEC-Q100 qualification for high reliability in temperatures up to 125 degrees Celsius.
Applications
Key Specifications
Getting Started
When designing the PCB layout, place a 1uF ceramic output capacitor close to the SOT-223 pins to ensure stability and improve transient response. Ensure the thermal pad or ground pins are connected to a sufficient copper plane to manage the heat dissipation of the 500mA load.
