Note 3: Do not apply current and voltage (including reverse polarity) to any pin that is not specified.
Note 4: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).

Note4: Ensure that the devices operate within the limits of the maximum rating when in actual use.
Note5: When the input voltage exceeds 29 V, the overvoltage protection circuit is activated to turn off
the output voltage.
