CL9901A28L3M

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

CL9901A28L3M 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 CL9901 regulator (接地端), used as the reference for the VOUT pin voltage range of GND-0.3 V to VIN+0.3 V.
2 VOUT power_out Regulated output pin; the datasheet limits the VOUT pin voltage to GND-0.3 V to VIN+0.3 V and the output current to 500 mA, with IOUT limited by Pd/(VIN-VOUT).
3 VIN power_in Supply input pin; the absolute maximum VIN pin voltage is -0.3 V to +6.0 V.
