LM1117DT-5.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

LM1117DT-5.0 from Texas Instruments, in a TO-252. 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 ADJ/GND power_in Adjust pin for adjustable output option; ground pin for fixed output option, so for the 5.0 V fixed version this pin is GND.
2 VOUT power_out Output voltage pin for the regulator, rated for up to 800 mA of output current per the datasheet.
3 VIN power_in Input voltage pin for the regulator; recommended VIN to GND is 15 V maximum and the absolute maximum is 20 V.
