MD53U36 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 | GND | power_in | Ground (VSS) pin; connect to a single-point ground and keep the output capacitor close to the VOUT and GND pins. |
| 2 | VIN | power_in | Positive supply input, rated for operation up to 10V (absolute maximum 12V), with a 10uF input capacitor in the application circuit. |
| 3 | VOUT | power_out | Regulated 3.6V output (±2%), up to 500mA, requiring a 2.2uF or larger capacitor with ESR of about 0.5~5 ohm to GND, and not to exceed VIN+0.3V. |
