IP1522
DUAL OUTPUT VOLTAGE SERIES REGULATOR
The IP1522 is a dual output voltage series regulator which
can provide up to 500mA of output current.
The IP1522 consists of 1-fixed 3.3V and 1-fixed 1.65V
regulators.
- 1-Fixed 3.3V Regulator with Internal NPN TR.
- 1-Fixed 1.65V Regulator with Internal NPN TR.
- Built-in TSD Circuit.
- Built-in Current Limit Circuit.
- Built-in ON/OFF Control Circuit.
- Built-in Over Voltage Protection Circuit.
- Output trimmed to +/-3% Tolerance

APPLICATION SUMMARY
- ON / OFF
When you want to control output of the IP1522, use pin #4 as follows
Pin#4
IP1522
HIGH
off
LOW
on
on/off function
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.
