L7805CDT-TR from STMicroelectronics, 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 INPUT power_in Unregulated DC input supply. Absolute maximum V_I = 35 V (for V_O = 5-18 V variants). A 0.33 uF ceramic capacitor should be placed close to this pin to ground for stability.
2 GROUND power_in Common ground reference. Internally tied to the exposed DPAK tab, which also serves as the primary thermal path (R_thJC = 8 °C/W for DPAK).
3 OUTPUT power_out Regulated +5 V output, up to 1.5 A (over 1 A with adequate heatsinking). A 0.1 uF ceramic output capacitor is recommended for transient response.
4 GROUND power_in DPAK thermal/ground tab. Electrically connected to pin 2 (GROUND) and is the primary heat-sinking surface for the package.
