APPLICATION SUMMARY
- ON / OFF
Pin#4
Vth
When you want to control output of the IP1520, use pin #4 as follows
(Rev.0)
on/off function
DUAL OUTPUT VOLTAGE SERIES REGULATOR
Q1

Main
bias
As shown in figure
Pin#4 is positive input of the comparator,
and the other Input is threshold voltage.
If the voltage of the pin#4 rises above threshold voltage,
then TR Q1 will be saturated and the main bias current
will be shut down.
