ETA1061S2G

etasolution · DC-DC Converters · SOT-23-6

ETA1061S2G 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 OUT power_out Output pin; bypass with a 4.7μF or larger ceramic capacitor placed closely between this pin and GND.
2 GND power_in Ground pin.
3 EN input Enable pin for the IC; drive high to enable the part and low to disable it.
4 IN power_in Input supply voltage; bypass with a 4.7μF ceramic capacitor to GND.
5 FB input Feedback input; add an external resistor divider from OUT to FB and GND to set the adjustable output voltage.
6 SW output Inductor connection; connect an inductor between SW and the regulator output.
