: This device is necessary to protect the element from damage when reverse voltage may be applied to the regulator
: This device is necessary when it is required to enhance the ripple rejection or to delay the output start-up time( 1).
: Be sure to mount the devices C
: These devices are necessary to set the output voltage. The output voltage V
in case of input short-circuiting.
