MC33269DTRK-3.3G from onsemi, in a DPAK. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground / common return for the regulator. Also serves as the Adj reference for adjustable versions (labelled GND/Adj in the datasheet); on this fixed 3.3 V variant it is the device ground. |
| 2 | Vout | power_out | Regulated 3.3 V output (3.27 to 3.33 V typical at Iout = 10 mA, TA = 25 degC). Sources up to 800 mA continuous. Requires a >=10 uF external output capacitor (0.2 to 10 ohm ESR) for stability. Electrically common with the DPAK heatsink tab. |
| 3 | Vin | power_in | Unregulated power supply input. Absolute maximum 20 V. Input bypass capacitor recommended (0.33 uF or larger low-ESR) to improve transient response and stability, particularly when the supply has long lead lengths. |
