Frequently Asked Questions

What is the dropout voltage of MCP1802T-3302I/OT and why does it matter for battery-powered designs?

The MCP1802T-3302I/OT has a typical dropout voltage of only 200 mV at full 300 mA load. This low dropout ensures regulated 3.3 V output remains stable even when the input supply drops close to the output, maximizing usable battery capacity in portable applications.

Can MCP1802T-3302I/OT supply enough current for a typical BLE microcontroller module?

Yes, it delivers up to 300 mA continuous output current at 3.3 V, which is sufficient for most BLE SoC modules that peak at 50 mA to 200 mA during radio transmission bursts, along with peripheral sensors and LEDs.

How does MCP1802T-3302I/OT compare to similar 3.3 V LDOs in terms of input voltage range?

The MCP1802T-3302I/OT accepts input voltages from 4.3 V up to 10 V absolute maximum, accommodating single-cell Li-ion with boost converter outputs, 5 V USB rails, and 9 V alkaline battery stacks in a single compact 5-pin SOT-23 footprint.
