Microchip Tech · Linear Voltage Regulators (LDO) · SOT-223
MIC37100-2.5WS from Microchip Tech, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Supply input for the regulator; the datasheet guarantees a 500 mV maximum dropout at full load and over temperature. |
| 2 | GND | power_in | Ground pin, which the datasheet's pin table also assigns to the TAB. |
| 3 | OUT | power_out | Regulator output, guaranteed to supply at least 1A and requiring a 10 µF or greater ceramic output capacitor for stability. |
