EUP7915  
On/Off Input Operation  
The EUP7915 is turned off by pulling the VEN pin low,  
and turned on by pulling it high. If this feature is not  
used, the VEN pin should be tied to VIN to keep the  
regulator output on at all time. To assure proper  
operation, the signal source used to drive the VEN  
input must be able to swing above and below the  
specified turn-on/off voltage thresholds listed in the  
Electrical Characteristics section under VIL and VIH.  
Fast Start up  
The EUP7915 output starts up after Vref voltage  
reaches its final value (1.2V nomial). The start-up time  
is determined by the time constant of the bypass  
capacitor. The smaller the capacitor value., the shorter  
the start-up time, but less noise gets reduced. As a  
result, start-up time and noise reduction need to be  
taken into design consideration when choosing the  
value of the bypass capacitor.
