K7812KT-500
WIDE INPUT, NON-ISOLATED & REGULATED
SMD PACKAGE SINGLE OUTPUT
RoHS
FEATURES
● Efficiency up to 95%
● No need for heat sinks
● 0.5AMP SMD package
● Wide input voltage range(14V~28V)
● Adjustable output voltage
● Remote ON/OFF control
●Short circuit protection, Thermal shutdown
● Very low shutdown current

APPLICATIONS
The K7812KT-500 with high efficiency
switching regulators is ideally supply for space
constrained mobile applications. They are no
need for any heat sinks, even if operate at
+85°C. The additional features include remote
ON/OFF control and adjustable output voltage.
Super low ripple and noise of typically only
10mV and a shutdown input current of typically
only 15uA.
