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.

If used with 5 V ≤ VCC < 8 V, short the VCC and VREG pins together. Note that in this case the electrical characteristics of the device become more easily influenced by fluctuations in the VCC supply voltage.
