input voltage and rated output load.
APPLICATIONS
The K78XXT-1000 series with high efficiency
switching regulators are ideally supply for
space constrained mobile applications. there
is no need for any heatsinks. The additional
features include remote ON/OFF control and
adjustable output voltage. Super low ripple
and noise of typically only 20mV and Low
control current.
