LM1117IMP-1.5

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LM1117IMP-1.5 from HGSEMI, in a SOT-223. 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 LM1117-1.5 (the datasheet lists this pin as GND/ADJ, with ADJ used only on the adjustable version); no pin-specific electrical limit is stated.
2 VOUT power_out Regulated output voltage pin; the fixed 1.5 V version is specified at 1.500 V nominal with 1% accuracy for the adjustable part and 2% for fixed versions, and maximum output current is 1 A.
3 VIN power_in Unregulated input supply pin; recommended input voltage is 15 V maximum and the absolute maximum input voltage is 20 V.
