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

SL42744D from Slkor SLKORMICRO Elec, in a TO-252. 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 Input supply pin. Accepts VI in the range (VQ+Vdr) < VI < 42 V. Place a 100 nF-470 nF ceramic bypass capacitor and a 10-470 uF bulk electrolytic capacitor close to this pin.
2 GND power_in Ground reference. Internally connected to the tab/heat sink of the TO-252 package.
3 Q power_out Regulated 5 V output. Typical VQ = 5.00 V, output current up to ~400 mA. Requires an output capacitor CQ >= 10 uF with ESR <= 10 ohm at 10 kHz to ground for stability; place close to the pin.
