5. The V
DD
5V output also supplies the output currents of SW 5V and ACC 5V. Therefore, the current supply capability of the V
DD
5V output and its other
electrical characteristics are affected by the output statuses of SW 5V and ACC 5V.
6. SW 5V and ACC 5V are not subject to a load.
7. When a component with a resistance accuracy of 1% is used
<Reference> When a component with a resistance accuracy of 0.5% is used, V
O
3” is 8.67V 9.0V 9.33V
8. When a component with a resistance accuracy of 1% is used
The absolute accuracy of the internal resistance is 15%
9. Since the SW 5V and ACC 5V are output from V
DD
5V through the SW, the voltage drops by an amount equivalent to the ON resistance of the SW.
10. The entire specification has been defined based on the tests performed under the conditions where Tj and Ta (=25C) are almost equal. There tests were
performed with pulse load to minimize the increase of junction temperature (Tj).
