Applications
The MCP1826-1802E/AT is commonly used to generate a stable 1.8 V core supply for FPGAs, DSPs, and microcontrollers in industrial control boards, embedded computing modules, and wireless communication equipment. Its 1000 mA current capability and low dropout voltage make it an efficient choice for powering memory interfaces and analog subsystems from 3.3 V or 5 V rails. The TO-220 package is also popular in benchtop instruments and evaluation boards where through-hole mounting and simple heatsinking are preferred.

Frequently Asked Questions
What is the maximum output current supported by MCP1826-1802E/AT and what load scenarios does it cover?
The MCP1826-1802E/AT can supply up to 1000 mA continuous output current at 1.8 V, which is sufficient to power microcontrollers, FPGAs, and DDR memory interfaces that typically require between 100 mA and 800 mA.
How low is the dropout voltage of the MCP1826-1802E/AT when powered from a 2.5 V Li-Ion cell?
The MCP1826-1802E/AT has a typical dropout voltage of 0.25 V and a maximum of 0.4 V, which means it can regulate a clean 1.8 V output from an input as low as 2.3 V, making it compatible with nearly depleted single-cell Li-Ion batteries.
Why might a designer choose the TO-220 5-pin package over a smaller surface-mount variant for a prototype board?
The TO-220-5 package supports through-hole mounting and allows easy attachment of a standard heatsink when dissipating more than 1 W, which is convenient during prototyping where thermal management flexibility and rework access matter more than PCB area.
