LM1117MDT-5.0

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

LM1117MDT-5.0 from HGSEMI, 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 GND/ADJ power_in Ground pin for the fixed-output LM1117-5.0; the same lead is the ADJ pin on the adjustable version.
2 VOUT power_out Regulated output voltage pin (5.0 V for this fixed version), with the tab internally connected to VOUT.
3 VIN power_in Input supply pin; the datasheet gives an absolute maximum input voltage of 20 V and a recommended input voltage of 15 V.
