Applications
The MCP1824T-1802E/DC is ideal for powering 1.8 V digital logic, microcontrollers, FPGAs, and low-voltage memory interfaces in battery-powered and USB-powered devices. Its 300 mA capability and low 0.2 V dropout make it well-suited for single-cell Li-ion battery systems where input rail headroom is limited. Wireless sensor nodes, portable instrumentation, and IoT edge devices benefit from its compact SOT-223 footprint and low quiescent current.

Frequently Asked Questions
What is the dropout voltage of the MCP1824T-1802E/DC, and why does it matter for battery-powered designs?
The MCP1824T-1802E/DC has a typical dropout voltage of 0.2 V and a maximum of 0.32 V at 300 mA output. In a single-cell Li-ion system where the battery can discharge to 2.5 V, the LDO can maintain the regulated 1.8 V output down to a battery voltage of just 2.1 V, extending useful battery runtime significantly.
How much output current can the MCP1824T-1802E/DC supply, and what loads is this appropriate for?
The MCP1824T-1802E/DC supplies up to 300 mA of continuous output current at 1.8 V, which is sufficient to power microcontrollers drawing under 100 mA, low-power FPGAs, flash memory arrays, and multiple sensor ICs simultaneously. The 5-pin SOT-223 package with exposed thermal tab helps dissipate heat for sustained full-load operation.
How does the MCP1824T-1802E/DC compare to adjustable LDOs for a fixed 1.8 V rail application?
Unlike adjustable LDOs that require 2 external resistors for output voltage setting, the MCP1824T-1802E/DC is factory-trimmed to 1.8 V, eliminating resistor tolerance errors and reducing BOM count by 2 components. This results in tighter output voltage accuracy, simpler layout, and lower total solution cost for high-volume products needing a fixed 1.8 V supply.
