SL7603P25PR

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

SL7603P25PR from Slkor SLKORMICRO Elec, in a SOT-89-3. 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 (Vss) pin, reference for the regulator; pin 1 at left in the SOT89-3 top view.
2 VIN power_in Input supply pin, input voltage range 3.5V to 15V (absolute maximum 18V).
3 VOUT power_out Regulated 2.5V output (±2%) delivering up to 500mA with built-in current limiter.
