CL9945A50P3M from CHIPLINK(芯联), in a SOT-89-3L. 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 terminal (接地端) of the regulator; the datasheet gives no electrical limit for this pin. |
| 2 | VIN | power_in | Supply input pin; the maximum input voltage is 24 V, and the absolute maximum VIN rating is -0.3 V to +28 V. |
| 3 | VOUT | power_out | Regulated output pin; output voltage is selectable from 1.5 V to 5 V in 0.1 V steps, with a maximum output current of 150 mA. |
