MET1117A50B3G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

MET1117A50B3G from MICRONE, in a SOT-223-4. 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 VSS power_in Ground pin for the fixed-output MET1117AXX devices; the output is rated from Vss-0.3 V to VIN+0.3 V relative to this pin.
2 VOUT power_out Regulated output pin, rated for an output current of 850 mA maximum (absolute maximum ratings) and an output voltage of Vss-0.3 V to VIN+0.3 V.
3 VIN power_in Power input pin with an absolute maximum input voltage of 20 V; the device requires VIN of at least VOUT+1.5 V for specified regulation.
4 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
