Notes

 

 

 

 

 

 

 

1.Using the IC under conditions exceeding the aforementioned absolute maximum ratings may lead to permanent destruction of the IC. Also, if an IC is operated at the absolute maximum ratings for a longer period of time, its functional reliability may be substantially deteriorated.

2.All the voltage ratings are based on VDD = 0V.

3.The output terminals (VO,VREG) are meant to output boosted voltage or stabilized boosted voltage. They, therefore, are not the terminals to apply an external voltage. In case the using specifications unavoidably call for application of an external voltage, keep such voltage below the voltage ratings given above.

Notes

1.The recommended circuit configuration for low-valtage operation (when VI is between –1.2V and –2.2V) is shown in the following figure. Note that diode D1 should have a maximum forward voltage of 0.6V with 1.0mA forward current.

2.RL min can be varied depending on the input voltage.
