MCP16301T-E from Microchip Tech, in a SOT-23-6. 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 | BOOST | passive | Boost voltage pin that drives the internal NMOS control switch, with a bootstrap capacitor connected between the BOOST and SW pins. |
| 2 | GND | power_in | Ground pin; keep the trace from the input capacitor return, output capacitor return and GND pin as short as possible to minimize noise. |
| 3 | VFB | input | Output voltage feedback pin connected to an external resistor divider to set the output voltage, regulating at 0.800V typical. |
| 4 | EN | input | Enable pin where logic high (>1.4V) enables operation and logic low (<0.4V) disables the regulator; do not allow this pin to float. |
| 5 | VIN | power_in | Input supply voltage pin for power and internal biasing, decoupled to GND with a 4.7 µF (up to 20 µF) capacitor placed close to the pin. |
| 6 | SW | output | Output switch node connected to the inductor, the freewheeling diode and the bootstrap capacitor. |
