FP6185-18S5 from Fitipower Integrated 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 | Power input pin that requires an input filter capacitor, with the datasheet noting 1µF to 10µF is sufficient, and operates from a VIN supply of 2V to 5.5V. |
| 2 | GND | power_in | Common ground pin for the regulator. |
| 3 | SHDN | input | Shutdown control: pull high to enable the IC and pull low to shut it down; floating the pin shuts the device down because of a built-in pull-low resistor (5MΩ per the block diagram). |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output that is stable with an output capacitor of 1µF or greater; a larger output capacitor reduces output noise and improves stability and PSRR. |
