Shanghai Mingda Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-3
MD5350 from Shanghai Mingda Microelectronics, in a SOT-89-3. 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 | Input supply pin, rated up to 10V operating input (12V absolute maximum), with at least 1.0 µF input capacitor recommended. |
| 2 | VOUT | power_out | Regulated 5.0V output (±2%) delivering up to 500mA, needing a 2.2 µF or larger output capacitor with 0.5-5Ω ESR and short-circuit current of about 50mA. |
| 3 | GND | power_in | Ground reference pin (VSS) for the regulator. |
