appears as input voltage is gradually decreased.
*8 : V
ROUT1
= A voltage equal to 98% of the output voltage whenever an amply stabilized I
OUT
{V
ROUT(T)
+ 1.0V} is input.
*9 : Current limit = When V
IN
is low, limit current may not be reached because of voltage falls caused by ON resistance or
serial resistance of coils.
*10: Integral latch circuit=latch time may become longer and latch operation may not work when V
IN
is 3.0V or more.
*11: V
DR(E)
= VD release voltage
*12: When temperature is high, a current of approximately 5.0
μ
A (maximum) may leak.
*13: When using the IC with a regulator output at almost no load, a capacitor should be placed as close as possible between
A
VDD
and A
GND
(C
IN2
), connected with low impedance. Please also see the recommended pattern layout for your
reference. Should it not be possible to place the input capacitor nearby, the regulated output level may increase up to
the V
DD
level while the load of the DC/DC converter increases and the regulator output is at almost no load.
