IL1117C-1.5

IKSEMICON · Linear Voltage Regulators (LDO) · SOT-223-4

IL1117C-1.5 from IKSEMICON, in a SOT-223-4. 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 power_in Ground pin on the fixed-voltage IL1117C-1.5 (the shared ADJ/GND pin is the adjust pin only on the adjustable version); the load low side can connect here.
2 OUTPUT power_out Regulated 1.5V output (1.470 to 1.530V over Io = 10mA to 1.0A) that needs at least a 10uF tantalum capacitor to GND for stability, and it is connected to the heat-sink tab.
3 INPUT power_in Unregulated input voltage, maximum 15V absolute maximum, with Vin = 3.0 to 12.0V specified for the 1.5V output and a 10uF tantalum input capacitor recommended.
4 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
