XBL1117-3.3

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

XBL1117-3.3 from XBLW, 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 power_in Ground pin of the fixed-output version (the adjustable version uses this pin as Adj.).
2 VOUT power_out Regulated output pin (fixed 3.3V for the XBL1117-3.3, output current capability 1.0A).
3 VIN power_in Input supply pin; recommended maximum input voltage is 15V and absolute maximum is 18V.
