D2632-ADJ from Silicore, in a TO-263-5. 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 | EN | input | Enable pin for ON/OFF control with TTL/CMOS-compatible thresholds (high/ON at 2.4 V min, low/OFF at 0.8 V max), and it may be tied to VIN or to a level up to 30 V when ON/OFF control is not needed. |
| 2 | VIN | power_in | Power supply input with a maximum continuous supply voltage of 26 V; transients up to 50 V are allowed only for under 100 ms at no more than 1% duty cycle, and the absolute rating is -20 V to +50 V. |
| 3 | GND | power_in | Ground reference pin; a 0.1 µF capacitor between VIN and GND is recommended when the input source has high AC impedance. |
| 4 | VOUT | power_out | Regulated output that requires a minimum output capacitor of 10 µF at full load, with a minimum load current of 7 mA to avoid leakage-driven output rise, and it delivers up to 3 A (full load). |
| 5 | ADJ | input | Adjust pin of the adjustable version used with an external two-resistor divider to set VOUT from 1.25 V up to 26 V, with a reference of 1.240 V typ and an adjust-pin bias current of 40 to 120 nA. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
