INTERPION IP1523

IP1523
DUAL OUTPUT VOLTAGE SERIES REGULATOR
DESCRIPTION
The IP1523 is a dual output voltage series regulator
with output on/off control function. The nominal output
voltages are 3.3V and 2.0V,respectively. The 3.3V
regulator can provide the output current up to 550mA.
While the 2.0V regulator can provide up to 500mA.
When the IP1523 becomes off, all the output voltages
are shut down.

APPLICATION SUMMARY
- ON / OFF Control Function
If you want to control the output of the IP1523, use pin #4 as follows:
Pin#4
IP1523
HIGH
off
LOW
on
If the voltage of pin#4 becomes larger than the threshold
voltage Vth, the main bias current and hence, the output
voltages will be shut down.
