Usage Notes
External components
1. This product requires eight Schottky barrier diodes and two Zener diodes.
We recommend the following components.
MN3111H
Schottky barrier diodes:
Zener diodes:
MA723 or equivalents
MA1150-M, MA8150-M (for positive regulated voltage) or equivalents
MA1100-M, MA8100-M (for negative regulated voltage) or equivalents

for positive
regulated voltage
for negative
regulated voltage
2. Always use the specified components for peripheral circuits so as to ensure that OVEE and VL do not reverse
potentials when the power is turned off.

Faulty operation
0.7V or higher
Reversal
OFF
As the above sketch illustrates, allowing OVEE to exceed VL1 and VL2 by more than 0.7 V produces the risk
of applying a forward bias to the PN junction, turning on the parasitic transistor, and generating an
overcurrent that produces latch-up.
If this phenomenon arises, increase the size of capacitor C7 or decrease the size of capacitor C13 to increase
the OVEE time constant.
(See the sample application circuit for the locations of C7 and C13.)
