Frequently Asked Questions
What is the maximum output current the MCP1825-3002E/DC can supply continuously?
The MCP1825-3002E/DC is rated for 500 mA continuous output current. With a typical dropout voltage of only 0.21 V at full load, the device maintains regulation with an input supply as low as 3.425 V, making it suitable for single-cell Li-Ion or two AA alkaline battery systems requiring a 3.0 V rail.
How does the MCP1825-3002E/DC perform in battery-powered IoT designs where standby current matters?
In standby-intensive IoT designs, the MCP1825-3002E/DC draws only 120 µA quiescent current, significantly extending battery life compared to regulators with milliamp-level quiescent draw. Operating from 3.425 V to 6 V input, it delivers a fixed 3.0 V output with up to 500 mA current capacity, well-suited for sensor nodes that sleep most of the time.
When would MCP1825-3002E/DC be a better choice than a switching regulator for a 3.0 V supply?
For noise-sensitive analog or RF front-end circuits requiring a clean 3.0 V rail below 500 mA, the MCP1825-3002E/DC offers lower output noise and simpler BOM than a switching converter. Its -40°C to +125°C operating range and SOT-223 package with exposed pad allow operation at full 500 mA load without external inductors, reducing cost and PCB area in compact designs.
