Application Information
Shutdown Mode
Taking the ADJ pin to a voltage below 0.2V for more than approximately 100µs will turn off the output and supply current to a low
standby level of 65µA nominal.
Note that the ADJ pin is not a logic input. Taking the ADJ pin to a voltage above V
100% nominal average value. (See page 17 graphs for details).
Soft-start
An external capacitor from the ADJ pin to ground will provide a soft-start delay, by increasing the time taken for the voltage on
this pin to rise to the turn-on threshold and by slowing down the rate of rise of the control voltage at the input of the comparator.
Adding capacitance increases this delay by approximately 0.2ms/nF. The graph below shows the variation of soft-start time for
different values of capacitor.
