7 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. Standard Application Circuit IN IN OUT TA78xxxAF 2 OUT C IN C 3 GND OUT.33 μf. μf Place C IN as close as possible to the input terminal and GND. Place C OUT as close as possible to the output terminal and GND. Although capacitor C OUT acts to smooth the dc 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. Usage Precautions 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 general silicon diode is 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. 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. 7
