SM5701_5.0V from HICHON, 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 | CE | input | Output enable pin; the electrical table gives the enable input high level as min 0.4*VOUT and low level as max 0.2V. |
| 2 | VOUT | power_out | Boosted output terminal, with an absolute maximum rating of -0.3V to 6.5V. |
| 3 | NC | unconnected | No connection (left floating). |
| 4 | GND | power_in | Ground terminal. |
| 5 | LX | passive | Switch node pin with an absolute maximum of -0.3V to 5V and a maximum switch current ILXmax of 1000mA. |
