Note:  
1. Answer for Vin-Vo>2V if needed to adjust the output voltage;  
2. If input voltage above specified may cause permanent damage to the device.  
3. K7812T-500, K7815T-500 is not allowed to operate under no load.  
APPLICATIONS  
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.
