FP6186AS5

Fitipower Integrated Tech · Linear Voltage Regulators (LDO) · SOT-23-5

FP6186AS5 from Fitipower Integrated Tech, 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 VIN power_in Supply voltage input, operating range 1.7V to 5.5V.
2 GND power_in Ground.
3 EN input Chip enable control input; pull high to enable the IC, pull low or leave floating to disable the device (internal pull-down resistor).
4 FB input Feedback voltage pin with 0.8V typical reference (0.79V to 0.81V), connected to an external resistor divider to set the output voltage.
5 VOUT power_out LDO output delivering up to 600mA, requiring a minimum 1µF output capacitor for stability.
