SL75BL33SC

Slkor(SLKORMICRO Elec.) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

SL75BL33SC from Slkor(SLKORMICRO Elec.), in a SOT-23-3. 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 pin, the common return for the input and output capacitors and the device.
2 VOUT power_out Regulated output voltage, fixed between 2.8V and 5.0V, which needs a minimum 10µF ceramic output capacitor (X7R or X5R) placed close to the pin for stability.
3 VIN power_in Power input voltage, rated up to 36V per the features list, with a 1µF ceramic input capacitor recommended close to the pin.

contacts copper must be back to the SL75B Series ground pin using as wide and as short of a copper trace as is 5

CAD (KiCad official)

  • Symbol: SL75BL33SC
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: sl75bl33sc-etched.step / sl75bl33sc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl75bl33sc.step / sl75bl33sc.glb are the bare package body.
