Applications
MCP1827-1202E/ET is primarily used in point-of-load power supplies for FPGAs, DSPs, and core voltage rails of processors where tight regulation and high output current are required from a modest input rail. Its high output current of 1.5 A and low dropout voltage also make it appropriate for post-regulation stages in battery-powered industrial handhelds and portable test equipment where supply headroom is limited.

Frequently Asked Questions
How does MCP1827-1202E/ET perform thermally when sourcing 1.5 A continuously in a compact design?
In the 5-pin D2PAK package, MCP1827-1202E/ET dissipates up to (VIN − VOUT) × IOUT watts; at a 1 V dropout and 1.5 A load that is 1.5 W. The exposed thermal pad on the D2PAK transfers heat efficiently to the PCB copper pour, keeping junction temperature below the 125°C maximum with adequate ground-plane copper area.
What input voltage headroom is needed above the 1.2 V output to guarantee full 1.5 A load regulation?
MCP1827-1202E/ET specifies a maximum dropout voltage of 0.6 V at 1.5 A load and 125°C junction temperature, so the input must remain at or above 1.8 V in worst-case conditions; with a typical dropout of 0.33 V, a 2.3 V input rail is sufficient for most operating scenarios.
Can MCP1827-1202E/ET replace MCP1825 in an existing 1.2 V LDO power design?
MCP1825 and MCP1827 share the same output voltage and input range, but MCP1827 delivers 1.5 A compared to MCP1825's 500 mA rating. If the load demands more than 500 mA, MCP1827-1202E/ET is a higher-current upgrade that fits the same D2PAK footprint with identical enabling logic.
Does MCP1827-1202E/ET carry RoHS and lead-free certifications for use in regulated end-product designs?
Yes, MCP1827-1202E/ET is fully RoHS-compliant and lead-free as indicated by the Pbfree code Yes in its product specifications, meeting EU RoHS Directive requirements. It is also rated to JESD-609 e3 moisture sensitivity and is suitable for inclusion in consumer and industrial products subject to environmental compliance regulations.
