LM7805L-TF3-T

UTC Unisonic Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220F

LM7805L-TF3-T from UTC Unisonic Tech, in a TO-220F. 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 IN power_in Unregulated input supply pin; per the absolute maximum ratings, VIN must not exceed 35 V for VOUT=5 to 18 V (40 V for VOUT=24 V).
2 GND power_in Ground pin, which must be at the minimum potential in all operating conditions.
3 OUT power_out Regulated 5 V output pin, supplying up to 1 A with thermal overload shutdown and output transistor SOA protection.
