Hi,
Customer want to be stat up time about 1mS.
TPS78833 has Programmable Slew Rate Control.
It is written in Datasheet that start-up time becomes 10mS as C(byp) is 0.01uF .
Can TPS78833's start-up time be more little by 10mS ?

Hi ,
An good way to approximate the required capacitor size is:
t = -R*C*ln(0.2)
Where R is the internal 150k resistor, C is C(byp) in farads, and t is the desired start-up time (1mS in your case).
Very Respectfully,
Ryan
