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 to 0.47 µF 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 µF or higher for the voltage and temperature range to be used.

COUT: 0.1 µF 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 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.
