s Standard Connection

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(*1).

(*1)Otherwise, it is not necessary.

(Care must be taken since Cref may raise the gain, facilitating oscillation.)

(*1)The output start-up time is proportional to Cre fX 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 and CO is 0.33

µF and 47µF, respectively. However, ajust 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 X (1+R2/R1)

(Vref is 1.25V TYP)

The standard value of R1 is 390

Ω.But value up 10kΩdoes not cause any trouble.
