2019-1.8YN5G from HXY MOSFET, in a SOT-23-5L. 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 | Power input pin; the absolute maximum input voltage is 7 V. |
| 2 | VSS | power_in | Ground pin for the regulator. |
| 3 | CE | input | Enable pin; the datasheet recommends driving it to 1.1 V to enable the output, and an internal 1 MΩ resistor is connected between CE and GND. |
| 4 | NC | unconnected | No connection; the pin is left floating (unused). |
| 5 | VOUT | power_out | Regulated output pin; the output voltage range is limited to VSS-0.3 V to VIN+0.3 V. |
