# MD7680AF0PA1

**Shanghai Mingda Microelectronics** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

MD7680AF0PA1 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 | GND | power_in | Ground reference pin for the regulator; the datasheet gives no separate limit for this pin. |
| 2 | VOUT | power_out | Regulated 15.0V output (MD7680AF0 nominal VOUT), and per the operation notes the VOUT pin must not be driven above VIN+0.3V because of the parasitic diode between VIN and VOUT. |
| 3 | VIN | power_in | Power input pin; the electrical characteristics specify an input voltage range of 2.2V to 60V, and the absolute maximum rating is -0.3V to 65V. |
