LN3435MR-G

NATLINEAR · DC-DC Converters · SOT-23-5L

LN3435MR-G from NATLINEAR, in a SOT-23-5L. 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 Chip enable input; driving it below 0.4V shuts the regulator down (shutdown current under 0.1uA), rising threshold is 1.5V.
2 GND power_in Ground pin.
3 SW passive Internal switch output node connecting to the inductor.
4 VIN power_in Power supply input, 2.7V to 6.0V operating range, with decoupling capacitor placed close to the pin.
5 FB input Output feedback sense input from the resistor divider, regulated to 0.588V to 0.612V.
