SL54M50SQ

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

SL54M50SQ from Slkor(SLKORMICRO Elec.), in a SOT-89. 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; the datasheet connects a 1µF input capacitor between VIN and GND and places the output capacitor close to VOUT and GND.
2 VIN power_in Power input voltage, 3V to 45V operating input range with an absolute maximum of -0.3 to +55V relative to GND, decoupled by a recommended 1µF ceramic capacitor to GND.
3 VOUT power_out Regulated output voltage (1.8V, 2.8V, 3.0V, 3.3V or 5.0V fixed options) delivering 300mA minimum with current-limit and short-circuit protection, requiring at least 1µF ceramic output capacitance for stability.
