Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-5L

MD7218E30PC1 from Shanghai Mingda Microelectronics, in a SOT-89-5L. 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 NC unconnected No connection pin.
2 GND power_in Ground pin; the top-side tab is also labelled 2 in the package drawing.
3 EN input Enable input, active high: VENH is 1.5V min to 18V and VENL is 0V to 0.5V.
4 VIN power_in Input supply, 2.2V to 18V operating (absolute maximum -0.3 to 20V).
5 VOUT power_out Regulated 3.0V output (MD7218E30) delivering up to 1A; must not exceed VIN+0.3V.
