L7808ABD2T-TR from STMicroelectronics, in a TO-263-2. 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 | INPUT | power_in | Unregulated positive DC input, VI. Absolute maximum 35 V (for VO = 5-18 V). Recommended input bypass capacitor CI = 0.33 µF near the pin. Minimum VI for 8 V regulation is ~10.6 V (dropout ~2 V at IO = 1 A). |
| 2 | GND | power_in | Common / ground reference. On the D²PAK this pin is electrically bonded to the exposed thermal tab, which serves as the primary heat sink path (RthJC = 3 °C/W). |
| 3 | OUTPUT | power_out | Regulated +8 V output, VO. Tolerance ±2 % (A grade): 7.84-8.16 V at TJ = 25 °C, 7.7-8.3 V over full IO/VI/temp range. Delivers up to 1.5 A (typ.) with internal current limiting (~2.2 A peak short-circuit). Recommended output capacitor CO = 0.1 µF for improved transient response. |
