CL9901A30S3M

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

CL9901A30S3M from CHIPLINK(芯联), in a SOT-23. 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 (接地端) for the SOT-23 package; the datasheet gives no electrical limit for this pin.
2 VOUT power_out Regulated output; the VOUT pin voltage is limited to GND-0.3 V to VIN+0.3 V and the output current is limited to 500 mA (Note 1: IOUT = Pd/(VIN-VOUT)).
3 VIN power_in Supply input; the VIN pin voltage is rated -0.3 V to +6.0 V.
