TA4800AF Electrical Characteristics Common to All Products • Tj = 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 0.3C3IN μ F I N TA4800AOFUT R1 3C.3O UμTF ADJ GND Load R2 • 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. Setting Output Voltage • The output voltage is determined by the equation shown below. When you control the output voltage with R1, a recommended value to use for R2 is 5 kΩ. R1 and R2must be placed as close as possible to each other, and the board trace to the ADJ terminal must be kept as short as possible. R1 V =V × ( 1+ ) OUT REF R2 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. CIN IN OUT COUT 0.33 μF TA4800AF R1 3.3 μF ADJ GND Load R2 • 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. • 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. 5 2013-11-01

TA4800AF • 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. 6 2013-11-01
