9.1 AS1310 Features  
Shutdown. The part is in shutdown mode while the voltage at pin Eelow 0.1V and is active when the voltage is higher than 0.7V.  
Note: EN can be driven above VIN or VOUT, as long as it limid to less than 3.6V.  
Output Disconnect and Inrush Limiting. During hutdown VOUT is going to 0V and no current from the input source is running through  
the device. This is true as long as the input voltage highr than the output voltage.  
Feedthrough Mode. If the input voltage is highhan the output voltage the supply voltage is connected to the load through the device. To  
guarantee a proper function of the AS13it is ot allowed that the supply exceeds the maximum allowed input voltage (3.6V).  
In this feedthrough mode the quiescent current is 35µA (typ.). The device goes back into step-up mode when the oputput voltage is 4% (typ.)  
below VOUTNOM.
