MC7805BDT

Tokmas · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

MC7805BDT from Tokmas, in a TO-252-2(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 Vin power_in Unregulated positive input voltage. Range 7.5V-25V for normal 5V operation; absolute maximum 35V. A 0.33uF bypass capacitor to GND is recommended close to the pin.
2 GND power_in Common ground reference for input and output. On DPAK-3 the heatsink tab is electrically connected to pin 2 (GND), providing the thermal path to the PCB copper.
3 Vout power_out Regulated +5V output, 4.75V-5.25V over line/load, up to 1.5A. A 0.1uF output capacitor to GND improves transient response. Short-circuit current typ. 230mA when shorted with Vi=35V; peak output current typ. 2.2A.
4 TAB power_in Heatsink tab on the DPAK-3 package, electrically connected to pin 2 (GND). Solder to a copper pour for thermal dissipation.
