RT8097AHGB from Richtek 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 | EN | input | Enable control input: logic-high (VIH min 1.5V) enables the converter and logic-low (VIL max 0.4V) forces shutdown. |
| 2 | GND | power_in | Power ground. |
| 3 | LX | output | Switch node, driving the inductor from the internal high-side and low-side power MOSFETs. |
| 4 | VIN | power_in | Supply voltage input; the RT8097A operates from a 2.7V to 6V input. |
| 5 | FB | input | Feedback voltage input; an external resistor divider from the output to GND sets the output voltage against the 0.6V (typ.) reference. |
