UA7808CKCS

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

UA7808CKCS from Texas Instruments, in a TO-220. 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 INPUT power_in Supply input voltage; recommended operating range 10.5V to 25V for μA7808 with internal current limiting and thermal-shutdown protection.
2 COMMON power_in Ground reference and common return path for input and output circuits.
3 OUTPUT power_out Regulated +8V output voltage (7.6V to 8.4V over 0°C to 125°C operating range) with maximum continuous output current of 1.5A and internal short-circuit current limiting.
