MCP1825S in Microchip MCP1700 / MCP1825 LDO Family
The MCP1825S series by Microchip Technology is a high-current, low-dropout (LDO) linear regulator sub-family capable of delivering up to 500mA of continuous output current. Characterized by its low output voltage capability and high stability with ceramic output capacitors, these regulators are designed for high-speed applications where transient response and thermal management are critical. The family serves as a robust power management solution for digital logic cores and sensitive analog circuits requiring fixed voltage rails from a wider input source.

| Part Number | Package | Output V | Stock |
|---|---|---|---|
| MCP1825S-3302E/DB (Microchip Technology) | 4-261 | 3.3V | 28,209 |
| MCP1825S-3302E/AB (Microchip Technology) | 3-220 | 3.3V | 548 |
| MCP1825S-1202E/DB (Microchip Technology) | 4-261 | 1.2V | 3,752 |
Variants within the MCP1825S sub-family are distinguished primarily by their fixed output voltage ratings and physical packaging. Options include standard SOT-223-3 for surface-mount efficiency and TO-220-3 for applications requiring superior heat sinking. While the internal CMOS architecture remains consistent, the 'S' designation indicates a 3-pin configuration, omitting the shutdown and power-good pins found on the full-featured MCP1825 variant to minimize footprint and complexity.
