: This device is necessary to protect the element from damage when reverse voltage may be applied to the regulator in case of
input short-circuiting.
C
ref
: This device is necessary when it is required to enhance the ripple rejection or to delay the output start-up time(*1).
(*1)Otherwise, it is not necessary.
(Care must be taken since C
ref
may raise the gain, facilitating oscillation.)
(*1)The output start-up time is proportional to C
