MET1117FB3G

MICRONE · Linear Voltage Regulators (LDO) · SOT-223-3

MET1117FB3G from MICRONE, in a SOT-223-3. 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 ADJ passive Adjust pin sets the output voltage through two external resistors, with a 1.25 V reference between the output and adjust pins and an adjust pin current of 30 uA maximum (11 uA typical).
2 VOUT power_out Regulated output delivering more than 700 mA with a maximum dropout of 1.5 V at 700 mA, and output current limited to 850 mA.
3 VIN power_in Power input rated for up to 20 V, with a minimum input of VOUT+1.5 V required for regulation.
