LM1117T-1.5

HGSEMI · Linear Voltage Regulators (LDO) · TO-220

LM1117T-1.5 from HGSEMI, 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 GND/ADJ power_in Ground pin for the fixed-voltage LM1117T-1.5; the same pin is the ADJ terminal on the adjustable version (datasheet lists it as 地/ADJ, with no numeric limit given for this pin).
2 VOUT output Regulated output voltage pin, and the metal tab is internally connected to VOUT.
3 VIN power_in Input operating voltage pin; absolute maximum input voltage is 20 V and recommended input voltage is 15 V.
