CL9956A36L3M

CHIPLINK(芯联) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

CL9956A36L3M 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 terminal of the regulator (接地端).
2 VOUT power_out Regulated output; the VOUT pin voltage is rated GND-0.3 V to VIN+0.3 V and the VOUT pin current is rated 500 mA, with IOUT limited to Pd/(VIN-VOUT) per the datasheet.
3 VIN power_in Supply input rated -0.3 V to +40 V absolute maximum (38 V in the electrical tables); for VIN above 20 V, the datasheet recommends electrolytic or tantalum input capacitance instead of ceramic to limit hot-plug voltage spikes.
