AP4306AUKTR-G1 from Diodes Incorporated, 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 | VCTRL | input | Input pin of the voltage control loop, with transconductance gain Gmv of 2.5 to 3.5 mA/mV and input bias current of 50 nA typical at 25°C. |
| 2 | GND | power_in | Ground reference pin for the controller. |
| 3 | VOUT | output | Output pin that sinks current only, with low output voltage of 100 mV typical at 10 mA sinking current. |
| 4 | ICTRL | input | Input pin of the current control loop, with transconductance gain Gmi of 1.5 mA/mV minimum and input bias current of 18 µA typical at 25°C. |
| 5 | VSENSE | input | Input pin of the current control loop, with a current control loop reference of 70 mV typical (A version, 66.5 to 73.5 mV at 25°C). |
| 6 | VCC | power_in | Power supply pin, with recommended operating supply voltage of 2.5 V to 18 V and absolute maximum rating of 20 V. |
