TA78033, 04, 05, 07, 08, 09AF 2006-11-06 6 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. Standard Application Circuit

  • 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 no rmal operation, the output terminal voltage becomes higher than the input voltage (GND po tential), 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 co nnected to the circuit, as shown in the above figure
  • There is a possibility that internal parasitic device s may be generated when momentary transients cause a terminal’s potential to fall below that of the GND termin al. 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. 1 2VIN TA78xxxAF VOUT COUTCIN 0.33 μF 0.1 μF IN OUT GND
