ETA1036V33S2F

etasolution · DC-DC Converters · SOT23-5

ETA1036V33S2F from etasolution, in a SOT23-5. 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 for the IC; drive to a voltage no higher than the input voltage 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. Operating input range is 0.6V to 4.5V.
5 SW output Inductor connection; connect an inductor between SW and the regulator output. SW/OUT voltage is rated -0.3V to 5.5V.
