HSPX3819M5-L-3-3 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 | Regulator input supply; the datasheet gives an input voltage range of 3.0 V to 20 V and asks that the input capacitor be placed close to the VIN pin. |
| 2 | VSS | power_in | Ground reference pin for the regulator. |
| 3 | CE | input | Chip enable input; a level of 0 V to 0.3 V (VCEL) disables the output and puts the part into standby with a maximum 0.2 µA sleep current, and the datasheet gives a 1.7 V minimum for the enable-high level (VCEH). |
| 4 | NC | unconnected | No connection (floating pin, marked 悬空 in the datasheet); leave unconnected. |
| 5 | VOUT | power_out | Regulated output; for the HSPX3819M5-L-3-3 variant the output voltage is 3.3 V, and the datasheet requires a ceramic output capacitor of at least 1 µF from VOUT to ground. |
