# BCT2193EUR12-TR

**BROADCHIP** · Linear Voltage Regulators (LDO) · SOT-23

BCT2193EUR12-TR from BROADCHIP, in a SOT-23. 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 for the regulator. |
| 2 | OUT | power_out | Regulator output; for this MPN (BCT2193EUR12-TR) the fixed output is 1.2V per the ordering table, with 500mA maximum output current. |
| 3 | IN | power_in | Regulator input; supply voltage range is 1.6V to 5.5V, and it should be bypassed with a 1μF capacitor to GND. |
