L7805ACD2T-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

L7805ACD2T-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 DC input voltage to the regulator; absolute maximum 35 V for the 5 V output version, with a minimum input-output differential (dropout voltage) of about 2 V at IO = 1 A needed to maintain regulation.
2 GROUND power_in Common/ground reference terminal for the regulator, internally tied to the package tab; the device has no external sense lead so ground-loop and lead-resistance drops should be minimized.
3 OUTPUT power_out Regulated positive output voltage, 5 V nominal (4.9 to 5.1 V at TJ = 25 °C for the A-version), capable of supplying up to 1.5 A output current with internal current limiting, thermal shutdown and SOA protection.
