CL9975A30P3N

ChipLink Tech · Linear Voltage Regulators (LDO) · SOT-89-3L

CL9975A30P3N from ChipLink Tech, in a SOT-89-3L. 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 (datasheet label: 接地端, ground).
2 VIN power_in Supply input; the datasheet rates the maximum input voltage at 18 V.
3 VOUT power_out Regulated output, programmable in 0.1 V steps from 1.2 V to 5.0 V with ±2% accuracy, delivering up to 150 mA (Pd ≤ 250 mW).
