SK6218-18NR

Suntek · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

SK6218-18NR from Suntek, in a SOT-23. 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 datasheet gives no further electrical limits for this pin).
2 VOUT power_out Regulated output voltage pin, selectable from 1.8V to 3.6V in 0.1V steps, with output current rated at 300mA and VOUT limited to VSS-0.3V to VIN+0.3V.
3 VIN power_in Input voltage pin, with an absolute maximum VIN of 8V and a 1.6V to 8V input range stated for line regulation.
