LD1117S12TR-HXY

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

LD1117S12TR-HXY from HXY MOSFET, 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 Vss/ADJ power_in Ground reference pin (labelled Vss/ADJ on the pin drawing and Adj/GND in the block diagram); it is the adjust pin on the ADJ version, where an optional CADJ bypass capacitor to ground improves ripple rejection.
2 Vout power_out Regulated output pin (1.2V on the LD1117S12TR) delivering up to 1A maximum output current, with a 10uF tantalum output capacitor recommended for stability.
3 Vin power_in Unregulated supply input pin with operating range up to 15V max and an absolute maximum of 18V, with a 10uF tantalum bypass capacitor recommended.
