Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3L
MD7612C50YA2 from Shanghai Mingda Microelectronics, in a SOT-223-3L. 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 | GND | power_in | Ground reference pin of the regulator. |
| 2 | VOUT | power_out | Regulated output voltage pin; VOUT must not exceed VIN+0.3V, since a higher VOUT can cause reverse current through the parasitic diode and destroy the IC. |
| 3 | VIN | power_in | Power input pin, specified for 2.2V to 40V operation with a 45V absolute maximum rating. |
