Note Internally limited.

When operating junction temperature rise above 150

°C, the internal protection circuit shutdown output voltage.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any

parameter. That is, the absolute maximum ratings are rated values at which the product is on the

verge of suffering physical damage, and therefore the product must be used under conditions that

ensure that the absolute maximum ratings are not exceeded.

CIN

: Need to stop the oscillation for the long input wire length.

CO

: Need to stop the oscillation for the long output wire length.

Improve the transient stability of the output voltage when the load current is suddenly changed.

CADJ : Improve the ripple rejection and the oscillate rejection.

D1

: Protect against CADJ when output pin is shorted.

D2

: Need for VIN

> VO.
