MIC5504-1.8YM5-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 | VIN | power_in | Supply input; the datasheet operating range is 2.5V to 5.5V, with an absolute maximum of -0.3V to +6V. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Active-high enable (High = ON, Low = OFF); enable voltage must stay between 0V and VIN, with logic-low at or below 0.2V and logic-high at or above 1.2V. On the MIC5504 the internal 4 MΩ pull-down holds the output off if this pin is left floating. |
| 4 | NC | unconnected | No connection; the pin is not internally connected. |
| 5 | VOUT | power_out | Regulated output voltage; on the MIC5504 an internal 25Ω auto-discharge load is switched on when the regulator is disabled to discharge the external capacitor. |
