LK7530-S

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

LK7530-S from LANKE, 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 VSS power_in Ground reference pin of the regulator (the block diagram labels this pin GND), with C1 and C2 of 1-10uF recommended in the typical application.
2 VOUT power_out Regulated output, fixed at 3.0V for the LK7530-S, with a rated output current of 150mA and a recommended 1-10uF capacitor C2.
3 VIN power_in Input supply pin, rated 30V in the electrical characteristics (36V absolute maximum), with a recommended 1-10uF capacitor C1.
