CL9936A33L3M 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 | Ground pin of the regulator, printed as 接地端 (ground) in the CL9936AXX pin table for the SOT-23-3L column. |
| 2 | VOUT | power_out | Regulated output; the datasheet limits the VOUT pin to 500 mA absolute maximum current (derated as Pd/(VIN-VOUT)) and GND-0.3 V to 7 V voltage. |
| 3 | VIN | power_in | Power input with absolute maximum rating of -0.3 V to +20 V and 18 V maximum input voltage in the electrical tables; the datasheet advises using electrolytic or tantalum input capacitors when VIN exceeds 12 V to avoid hot-plug overvoltage spikes above 18 V. |
