output voltage ramps up as soon as the input voltage reaches the UVLO threshold as set by the R1and
R2 resistor divider network. In
using a jumper at JP1 to tie EN to GND. When the jumper is removed, EN is released. When the EN
voltage reaches the enable-threshold voltage, the start-up sequence begins and the output voltage ramps
up to the externally set value of 5 V. The input voltage for these plots is 24 V and the load is 5 Ω.
