Note 2: Do not apply current and voltage (including reverse polarity) to any pin that is not specified.
Note 3: 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 vary with temperature.
The ratings at Tj = 25℃assume that a temperature increase has no effect on IC characteristics as ascertained by
pulse tests.

• Place CIN as close as possible to the input terminal and GND. Place COUT as close as possible to the output
terminal and GND. Although capacitor COUT acts to smooth the dc output voltage during suspension of
output oscillation or load change, it might cause output oscillation in a cold environment due to increased
capacitor ESR. It is therefore recommended to use a capacitor with small variations temperature sensitivity.
The IC may oscillate due to external conditions (output current, temperature, or the type of the capacitor
used). The type of capacitor required must be determined by the actual application circuit in which the IC is
used.
The notice in case of application
• If the input terminal shorts to GND in a state of normal operation, the output terminal voltage becomes
higher than the input voltage (GND potential), and the electric charge of a chemical capacitor connected to
the output terminal flows into the input side, which may cause the destruction of circuit.
In these cases, take such steps as a zener diode and a general silicon diode are connected to the circuit, as
shown in the above figure
• There is a possibility that internal parasitic devices may be generated when momentary transients cause a
terminal’s potential to fall below that of the GND terminal. In such case, that the device could be destroyed.
The voltage of each terminal and any state must therefore never fall below the GND potential.
