The K78xxT-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°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. |
