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

SL9193M33SA from Slkor SLKORMICRO Elec, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the LDO. Return path for both input and output capacitors; route with a wide, short copper trace directly to the ground pin.
2 VOUT power_out Regulated output voltage, fixed at 3.3 V for the -33 option. Supplies up to 300 mA (typical current limit 450 mA). Requires a 1 uF ceramic (X7R/X5R) output capacitor placed close to the pin for stability.
3 VIN power_in Unregulated input supply, 2 V to 6.5 V operating range (absolute max -0.3 V to 7 V). Requires a 1 uF ceramic decoupling capacitor to GND placed close to the pin. In the 3-pin SOT-23 (SA) variant the internal EN input is bonded to VIN so the regulator is always on.
