MIC5247-1.8YM5-TR from Microchip Tech, in a SOT-23-5. 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, specified for VIN from +2.7V to +6V in the operating ratings with a 7V absolute maximum. |
| 2 | GND | power_in | Ground pin, which carries the ground pin current of 85µA typical at 0mA load per the electrical characteristics. |
| 3 | EN | input | CMOS-compatible enable input: logic high enables the regulator and logic low shuts it down, and it must not be left open (VEN range 0V to VIN). |
| 4 | BYP | passive | Reference bypass pin: connect an external 0.01µF capacitor to GND to reduce output noise, and it may be left open. |
| 5 | OUT | power_out | Regulator output, which requires an output capacitor of 1µF or greater for stability. |
