Application Circuit
The capacitors C
IN
/C
OUT
must be guaranteed to operate within the temperature range in which the regulator
operates correctly.
The equivalent series resistance (ESR) of C
OUT
must be less than 1 Ω inside the operating temperature range.
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.
• Overvoltage Protection
The overvoltage protection circuits in the Product are designed to temporarily protect Product from minor
overvoltage of brief duration. When the overvoltage protective function in the Product activates,
immediately cease application of overvoltage to Product. Improper usage of Product, such as application of
voltage to Product exceeding the absolute maximum ratings, could cause the overvoltage protection circuit
not to operate properly and/or damage Product permanently even before the protection circuit starts to
operate.
