APPLICATIONS

The WRN78xxT-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.
