TLE4276GV from Infineon Technologies, 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 | I | power_in | Input supply, operating up to 40 V (abs max -42 to 45 V); block to ground directly at the IC with a ceramic capacitor. |
| 2 | INH | input | Active-low inhibit input; pulling it low switches the regulator off and drops current consumption below 10 µA. |
| 3 | GND | power_in | Ground. |
| 4 | VA | input | Voltage adjust input for the adjustable version (TLE4276GV); connect an external divider to set the output voltage between 2.5 V and 20 V (internal reference typ. 2.5 V). |
| 5 | Q | power_out | Regulated output, up to 400 mA; block to GND with a capacitor of at least 22 µF and ESR ≤ 3 Ω at 10 kHz. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
