The product(s) in this document (“Product”) contain functions intended to protect the Product from
temporary small overloads such as minor short-term overcurrent or overheating. The protective
functions do not necessarily protect Product under all circumstances. When incorporating Product into
your system, please design the system (1) to avoid such overloads upon the Product, and (2) to shut
down or otherwise relieve the Product of such overload conditions immediately upon occurrence. For
details, please refer to the notes appearing below in this document and other documents referenced in
this document.

Note 1: External current and voltage ((including negative voltage) should not be applied to pins not specified.
Note 2: 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).

Electrical Characteristics for All Products
Generally, the characteristics of power supply ICs change according to temperature fluctuations.
The specification Tj = 25°C is based on a state where temperature increase has no effect (assuming no fluctuation
in the characteristics) as ascertained by pulse tests.
Standard Application Circuit
Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND.
The capacitances should be determined experimentally. In particular, adequate investigation should be made so
that there is no problem even in high or low temperatures.
Usage Precautions
• Low voltage
Do not apply voltage to the Product that is lower than the minimum operating voltage, or the Product’s
protective functions will not operate properly and the Product may be permanently damaged.
• Overcurrent Protection
The overcurrent protection circuits in the Product are designed to temporarily protect Product from minor
overcurrent of brief duration. When the overcurrent protective function in the Product activates,
immediately cease application of overcurrent to Product. Improper usage of Product, such as application of
current to Product exceeding the absolute maximum ratings, could cause the overcurrent protection circuit
not to operate properly and/or damage Product permanently even before the protection circuit starts to
operate.
• Overheating Protection
The thermal shutdown circuits in the Product are designed to temporarily protect Product from minor
overheating of brief duration. When the overheating protective function in the Product activates,
immediately correct the overheating situation. Improper usage of Product, such as the application of heat
to Product exceeding the absolute maximum ratings, could cause the overheating protection circuit not to
operate properly and/or damage Product permanently even before the protection circuit starts to operate.
