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.

CIN: 0.1
F or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure
to connect CIN 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 CIN is 0.1
F or higher for the voltage and temperature range to be used.
COUT1, COUT2: 10
F or higher. Be sure to connect COUT1 and COUT2 to prevent oscillation and improve excessive load
regulation. Place CIN, COUT1 and COUT2 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.
D11, D12: If the OUTPUT1 pin or OUTPUT2 pin has a higher voltage than the INPUT pin, connect a diode.
D21, D22: If the OUTPUT1 pin or OUTPUT2 pin has a lower voltage than the GND pin, connect a Schottky barrier
diode.
Caution Make sure that no voltage is applied to the OUTPUT1
pin or OUTPUT2 pin from external.
