SPECIFICATIONS
Absolute Maximum Ratings
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 V
DD
= 0V.
3. The output terminals (V
O
,V
REG
) 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.
Reconmmended Operating Conditions
V
DD
= 0V, Ta = –40 to +85˚C unless otherwise noted
Notes
1. The recommended circuit configuration for low-valtage operation (when V
I
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. R
L
min can be varied depending on the input voltage.
