MD7612D33UA2

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

MD7612D33UA2 from Shanghai Mingda Microelectronics, in a TO-252-2. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Device ground reference. Return for both input and output currents; should be connected to the system ground plane.
2 VOUT power_out Regulated 3.3V output pin. Drain of the internal P-channel MOSFET pass transistor. Requires COUT ≥ 2.2uF ceramic capacitor for stability. Maximum output current 1A; dropout typ. 10 mV @ 10 mA, 1000 mV @ 1 A.
3 VIN power_in Power input pin. Accepts 2.2 V to 40 V (absolute max 45 V). Requires CIN ≥ 2.2uF placed close to the pin; increase CIN as VIN rises.
