GR1810-2 from GR, 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 | NC | unconnected | No connection. Leave floating; not internally bonded. |
| 2 | OUT | output | LED constant-current output (sink). Regulates to 18mA typical (17.46-18.54mA) once VOUT exceeds ~2.5V; recommended operating VOUT around 3V, absolute max 24V. Connect in series with the LED string return path to GND. |
| 3 | GND | power_in | Power/signal ground reference for the internal current source. |
