While the Vout voltage will be 5 V
±
1.5% when the
Voadj pin is open, the circuit shown here should be
used to change the Vout voltage externally.

When this function operates, the base current to the
external transistor connected to the CS pin stops and
the Vout output is lowered.

This function prevents the microprocessor from being
damaged if the Vout voltage is inadvertently increased
to too high a level. The OVP detection voltage is fixed.
