MD7218D60UA2

Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L

MD7218D60UA2 from Shanghai Mingda Microelectronics, in a TO-252-2L. 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 Input supply pin for the regulator, with an operating input voltage of 2.2V to 18V and an absolute maximum rating of -0.3V to 20V.
2 GND power_in Ground reference pin for the regulator.
3 VOUT power_out Regulated output pin delivering up to 1A, which must not be driven above VIN+0.3V to avoid reverse current damage through the internal parasitic diode.
