D1
: 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.
Cref
: This device is necessary when it is required to enhance the ripple rejection or to delay the output start-up
time*. Otherwise, it is not necessary.
(Care must be taken since Cref may raise the gain, facilitating oscillation.)
*The output start-up time proportional to Cref✕R2.
CIN, CO : Be sure to mount the devices CIN and CO as close to the device terminal as possible so as to prevent oscillation.
The standard specification of CIN= 0.33µ ,CO= 47µ, respectively. However, adjust them as necessary after checking.
R1, R2 : These devices are necessary to set the output voltage. The output voltage VO is given by the following formula:
VO=Vref✕(1+R2/R1)
(Vref is 1.25V TYP)
The standard value of R1 is 2
Ω. But value up to 10kΩ.
