Note Internally limited. When the operating junction temperature rises above 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.

OUTPUT
CIN
: 0.1
F or higher. Be sure to connect CIN to prevent parasitic oscillation. Set this value according to the
length of the line between the regulator and the INPUT pin. Use of a film capacitor or other capacitor
with first-rate voltage and temperature characteristics is recommended. If using a laminated ceramic
capacitor, it is necessary to ensure that CIN is 0.1
F or higher for the voltage and temperature range
to be used.
COUT
: 47
F or higher. Be sure to connect COUT to prevent oscillation and improve excessive load regulation.
Place CIN and COUT as close as possible to the IC pins (within 1 to 2 cm). Also, use an electrolytic capacitor
with low impedance characteristics if considering use at sub-zero temperatures.
D1
: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
D2
: 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.
