An appropriate CL value must be placed on VOUT such that the IMAX and IPLS specifications of the device are not

violated.

10.5.3 Application Curves

See the oscilloscope captures below for an example of how the CT capacitor can be used to reduce inrush

current for VIN = 12 V. See the Adjustable Rise Time (CT) section for rise times for corresponding CT values.
