ETA8110S2G from etasolution, 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 | BST | passive | Bootstrap pin for the high-side driver; the datasheet specifies a 10nF capacitor connected from this pin to SW and gives a BST voltage limit of -0.3V to SW+6V. |
| 2 | GND | power_in | Ground reference for the regulator; the layout guide recommends connecting GND to a large copper area for heat spreading. |
| 3 | FB | input | Feedback input that receives an external resistor divider from the output to set VOUT (VREF 0.6V typical); FB voltage limit is -0.3V to 6V. |
| 4 | EN | input | Enable input: drive high to enable the part, low or floating to disable it; EN voltage limit is -0.3V to 24V and it has an internal 1MΩ pull-down to GND. |
| 5 | IN | power_in | Supply voltage input with a 3.5V to 18V operating range; bypass with a 10μF ceramic capacitor to GND, placed close to the pin. |
| 6 | SW | output | Inductor connection: connect an inductor between SW and the regulator output; SW voltage is rated -0.3V (-5V for <10ns) to 19V (23V for <10ns). |
