MD7680DC0UA2

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

MD7680DC0UA2 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 Power input pin; operating input range is 2.2V to 60V (absolute maximum -0.3 to 65V).
2 GND power_in Ground pin (also the tab of the TO252-2L package).
3 VOUT power_out Regulated output voltage pin (12.0V for MD7680DC0), delivering up to 150mA and must not exceed VIN+0.3V.
