EN pin on TPS7H1201

Other Parts Discussed in Thread: TPS7H1201-HT

Hi, 

I am using this converter to convert from 1.5V to 1.2V. But not sure how to use the EN pin and the SS pin. 

Are you guys missing something in the datasheet here ?

It says EN pin needs to be connected to +3.5V or higher. What if i don't have something higher ? 

Secondly, how to select value of capacitor to be installed at SS pin ? Datasheet never specifies. Or am I missing something here ?

Thanks,

    [For TPS7H1201-HT  For Vin = 1.5V and Vout = 1.2V

    1. Connect Enable pin high to Vin as highlighted in the datasheet.

    2. Use Soft Start pin to disable the LDO, by pulling down on the SS pin 1.

    3.  In order to calculate the soft start value it is highlighted in the datasheet equation 4.
