CL9975A50L3N from CHIPLINK(芯联), in a SOT-23-3L. 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 | 接地端 (ground terminal) of the LDO; the datasheet gives no electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated output terminal, rated for a maximum output current of 150 mA (Pd ≤ 250 mW) with output voltage accuracy of ±2%. |
| 3 | VIN | power_in | Power input terminal; the maximum input voltage is 18 V. |
