MD7680E33PA1 from Shanghai Mingda Microelectronics, in a SOT-89-3L. 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 | VOUT | power_out | Regulated output voltage pin; VOUT must not exceed VIN+0.3V, otherwise reverse current through the parasitic diodes can destroy the IC. |
| 2 | GND | power_in | Ground pin; the device's ground reference, and for the short-circuit test VOUT is shorted to GND through less than 0.1 ohm. |
| 3 | VIN | power_in | Power input pin; input voltage range is 2.2 V to 60 V, with an absolute maximum rating of -0.3 V to 65 V. |
