MD7218E36PC1

Shanghai Mingda Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-5L

MD7218E36PC1 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 VIN power_in Input supply pin; the electrical characteristics give an input voltage range of 2.2V to 18V, and the absolute maximum input voltage is 15V.
2 GND power_in Ground reference pin, shown as the centre pin of the SOT89-5L package; the datasheet gives no separate limit for it.
3 EN input Enable pin; the datasheet does not state its threshold levels or its behaviour.
4 VOUT power_out Regulated output pin delivering up to 1A; the VOUT potential must not exceed VIN+0.3V, otherwise reverse current can destroy the IC.
5 NC unconnected Marked NC in the pin figure; the datasheet gives no function for this pin.
