MIC5504-2.8YM5-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 | VIN | power_in | Supply input; the datasheet gives an operating supply voltage range of 2.5V to 5.5V (absolute maximum -0.3V to 6V). |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Active-high enable input (high = ON, low = OFF) with logic low at 0.2V max and logic high at 1.2V min; the MIC5504 has an internal pull-down so this pin may be left floating. |
| 4 | NC | unconnected | No connection; the pin is not internally connected. |
| 5 | VOUT | power_out | Output voltage; when the regulator is disabled the MIC5504 switches an internal 25Ω load to discharge the external output capacitor. |
