# 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. |
