IP1532
TRIPLE OUTPUT VOLTAGE SERIES REGULATOR
APPLICATION SUMMARY
- ON / OFF
When you want to control output of the IP1532, use pin #4 as follows
Pin#4
IP1532
Main
HIGH
off
bias
LOW
on
Q1
Pin#4
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,
Vth
then TR Q1 will be saturated and the main bias current
will be shut down.
