Electrical Characteristics for All Products
• T
j
= 25°C in the measurement conditions of each item is the standard condition when a pulse test is carried
out, and any drift in the electrical characteristic due to a rise in the junction temperature of the chip may be
disregarded.
Standard Application Circuit
• Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND.
The use of a monolithic ceramic capacitor (B Characteristic or X7R) of low ESR (equivalent series resistance)
is recommended. 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.
Usage Precautions
• The IC might be destroyed if a voltage greater than the input terminal voltage is applied to the output
terminal, or if the input terminal is connected to GND during operation. To prevent such an occurrence,
connect a diode as in the following diagram.
• 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.
