Sanyo LA4535M Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Note) The quiescent current is respresented by the current flowing into pin 6. The respective maximum currents flowing

into pin 1 and pin 10 are calculated by (V pin –0.5) / 16 [V/kΩ] and the total current increases by these current
values.
