**etasolution** · DC-DC Converters · SOT-23-5

ETA1036V50S2F from etasolution, 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 | OUT | power_out | Output pin; bypass with a 22μF or larger ceramic capacitor placed closely between this pin and GND. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin; drive to a voltage no higher than the input voltage to enable the part, and low to disable it (EN input low maximum 0.3V, input high minimum 0.6V). |
| 4 | IN | power_in | Input supply voltage; bypass with a 4.7μF ceramic capacitor to GND (VIN range 0.6V to 4.5V). |
| 5 | SW | output | Inductor connection; connect an inductor between SW and the regulator output (SW/OUT voltage absolute maximum -0.3V to 5.5V). |
