Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-5

SL4275 from Slkor SLKORMICRO Elec, in a TO-252-5. 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 I power_in Regulator input supply. Operating range 5.5V to 55V (absolute max 60V). Bypass with a ceramic capacitor placed close to the IC pin to ground.
2 RQ output Open-drain reset output. Pulled low when VQ falls below the reset threshold VRT (typ 4.65V). Requires an external pull-up resistor (Rext >= 5kΩ); VOL <= 0.4V. Absolute max 36V. May be left floating if unused.
3 GND power_in Ground reference. Internally connected to the exposed heat-sink tab (die pad).
4 D passive Reset delay timing pin. Connect a capacitor to GND to set the reset delay (trd = CD * 1.8V / 6uA; e.g. 47nF ≈ 15ms). Charge current ≈ 6uA typ, upper trip VDT ≈ 1.8V. Absolute max 12V. May be left floating (default delay ~8us).
5 Q power_out Regulated 5.0V output (±2%, 4.9V-5.1V). Supplies up to 450mA (current limit typ 800mA). Requires an output capacitor CQ >= 22uF with ESR <= 5Ω @ 10kHz for loop stability. Absolute max 12V.
