FOperation notes
(1)
When operating within the normal voltage range and
within the ambient operating temperature range, most
circuit functions are guaranteed.
The rated values cannot be guaranteed for the electrical
characteristics, but there are no sudden changes of the
characteristics within these ranges.
(2)
Heat attenuation characteristics are noted on a separate
page and can be used as a guide in judging power dis-
sipation.
If these ICs are used in such a way that the allowable
power dissipation level is exceeded, an increase in the
chip temperature could cause a reduction in the current
capability or could otherwise adversely affect the perfor-
mance of the IC. Make sure a sufficient margin is allowed
so that the allowable power dissipation value is not ex-
ceeded.
(3)
Be sure to connect a capacitor between the output pin
and GND to prevent oscillation. Since fluctuations in the
valve of the capacitor due to temperature changes may
cause oscillations, a tantalum electrolytic capacitor with
a small internal series resistance (ESR) is recom-
mended.
A 22 F capacitor is recommended; however, be aware
that if an extremely large capacitance is used (1000 F
or greater), then oscillations may occur at low frequen-
cies. Therefore, be sure to perform the appropriate verifi-
cations before selecting the capacitor.
Also, we recommend connecting a 0.33 F bypass ca-
pacitor as close as possible between the input pin and
GND.

An overcurrent protection circuit is built into the outputs,

to prevent destruction of the IC in the even the load is
shorted.
This protection circuit limits the current in the shape of a
’7’. This circuit is designed with a high margin, so that that
current is restricted and latching is prevented, even if a
high-capacitance capacitator causes a large amount of
current to temporary flow through the IC.
However, these protection circuits are only good for pre-
venting damage from sudden accidents and should not
be used for continuous protection (for instance, clamping
at an output of 1V
circuit operates). Note that the capacitor has negative
temperature characteristics, and the design should take
this into consideration.
(5)
A built-in thermal overload circuit prevents damage from
overheating. When the thermal circuit is activated, the
outputs are turned OFF. When the temperature drops
back to a constant level, the circuit is restored.

be damaged if absolute maximum ratings for voltage or
operating temperature are exceeded. If damage has oc-
curred, special modes (such as short circuit mode or
open circuit mode) cannot be specified. If it is possible
that such special modes may be needed, please consid-
er using a fuse or some other mechanical safety mea-
sure.
