APPLICATIONS
The WRN78xxT-500 series with high efficiency
switching regulators are ideally supply for space
constrained mobile applications . They are no need for
any heat sinks , even if operate at +85 ℃. 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 .
