Application Information (cont.)
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 20μA nominal.
Note that the ADJ pin is not a logic input. Taking the ADJ pin to a voltage above V REF will increase output current above the
100% nominal average value. (See graphs for details).
Soft-start
The device has inbuilt soft-start action due to the delay through the PWM filter. An external capacitor from the ADJ pin to
ground will provide additional 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. With no external
capacitor, the time taken for the output to reach 90% of its final value is approximately 500 μ s. Adding capacitance increases
this delay by approximately 0.5ms/nF. The graph below shows the variation of soft-start time for different values of capacitor.
