SY8089A from TECH PUBLIC, 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 | EN | input | Enable control; pull high to turn on and do not float (VIH min 1.1V, VIL max 0.9V). |
| 2 | GND | power_in | Ground pin. |
| 3 | LX | output | Inductor pin; connect to the switching node of the inductor (voltage range -0.3V to VIN+0.3V). |
| 4 | IN | power_in | Input supply pin, 2.5V to 5.5V operating; decouple to GND with at least 22uF ceramic capacitor. |
| 5 | FB | input | Output feedback pin; connect to the center of the output resistor divider to set Vout=0.6*(1+R1/R2). |
