SK6218-18NR is a SOT-23 Linear Voltage Regulator (LDO) manufactured by Suntek, with a RoHS Compliant package. It is a two-terminal low-dropout (LDO) bipolar transistor, current limiting, and thermal shutdown for providing regulated voltage outputs. The device features an operating voltage range of 2.7V to 6.8V, a maximum output current of 1.5A, and a maximum dropout voltage of 700mV at 1A. The SK6218-18NR has excellent line and load regulation for providing stable voltage outputs, low quiescent current, fast turn-on time and low temperature coefficient. Its PIN-DIODE protection prevents bypass when power is turned off, while its thermal shutdown feature protects against current overload.
