LMUN2233LT1G from LRC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Base | input | Base input pin. Drives the NPN transistor through the monolithic series bias resistor R1 = 4.7 kΩ; R2 = 47 kΩ sits between the internal base node and the emitter. Input high turns the transistor on. |
| 2 | Emitter | passive | Emitter of the internal NPN transistor. Typically tied to circuit ground / signal return. |
| 3 | Collector | output | Open-collector output of the internal NPN transistor. Typically pulled up to a supply through the load; IC up to 100 mA, VCEO = 50 V max. |
