Note
Internally limited. When the operating junction temperature rises over 150°C, the internal circuit shuts down the
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.

C

: 0.1 to 0.47
µ
F or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be
sure to connect C
IN
to prevent parasitic oscillation. Use of a film capacitor or other capacitor with excellent voltage
and temperature characteristics is recommended. If using a laminated ceramic capacitor, it is necessary to ensure
that C
IN
is 0.1
µ
F or higher for the voltage and temperature range to be used.
C
OUT
: 0.1
µ
F or higher. Be sure to connect C
OUT
to prevent oscillation and improve excessive load regulation. Place C
IN
and C
OUT
as close as possible to the IC pins (within 2 cm). Also, use an electrolytic capacitor with low impedance
characteristics if considering use at sub-zero temperatures.
D
1
: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
D
2
: If the OUTPUT pin has a lower voltage than the GND pin, connect a Schottky barrier diode.
Caution Make sure that no voltage is applied to the OUTPUT pin from external.

Caution Use of conditions other than the above-listed recommended operating conditions is not a problem as
long as the absolute maximum ratings are not exceeded. However, since the use of such conditions
diminishes the margin of safety, careful evaluation is required before such conditions are used.
Moreover, using the MAX. value for all the recommended operating conditions is not guaranteed to be
safe.
