Note 1. Internally limited. When the operating junction temperature rises over 150°C, the internal circuit shuts down

the output voltage.

2. Mounted on ceramic substrate of 75 mm2 x 0.7 mm

3. Mounted on ceramic substrate of 16 cm2 x 0.7 mm

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 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. 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: 10 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). Be sure to use the capacitor of 10 µF or higher

of capacity values and 1 to 8 Ω of equivalent series resistance under an operating condition.

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.
