Further, special care is necessary in case of a voltage boost application. (2) When a surge voltage exceeding maximum rating is applied to the input terminal or when a voltage in excess of the input terminal voltage is applied to the output terminal, the circuit may be destroyed. Specially, in the latter case, great care is necessary Further, 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 zener diode and a general silicon diode are connected to the circuit, as shown in the following figure. Output surge and input short protecting diode. VIN KIA78xx SERIES VOUT VZ Input surge protecting diode. VZ >VIN (3) When the input voltage is too high, the power dissipation of three terminal regulator increase because of series regulator, so that the junction temperature rises. In such a case, it is recommended to reduce the power dissipation by inserting the power limiting resistor RSD in the input terminal, and to reduce the junction temperature as a result. 2010. 5. 19 Revision No : 1 16/20 KIA7805AP~KIA7824AP R SD VIN I OUT VIN 0.33µF KIA78xx SERIES V OUT IB The power dissipation PD of IC is expressed in the following equation. PD = (VIN'-VOUT) IOUT + VIN' IB If VIN' is reduced below the lowest voltage necessary for the IC, the parasitic oscillation will be caused according to circumstances. In determining the resistance value of RSD, design with margin should be made by making reference to the following equation. V - VIN' RSD < IN IOUT + IB (4) Connect the input terminal and GND, and the output terminal and GND, by capacitor respectively. The capacitances should be determined experimentally because they depend on printed patterns. In particular, adequate investigation should be made so that there is no problem even at time of high or low temperature. (5) Installation of IC for power supply For obtaining high reliability on the heat sink design of the regulator IC, it is generally required to derate more than 20% of maximum junction temperature (Tj MAX.) Further, full consideration should be given to the installation of IC to the heat sink. (a) Heat sink design The thermal resistance of IC itself is required from the viewpoint of the design of elements, but the thermal resistance from the IC package to the open air varies with the contact thermal resistance. Table 1 shows how much the value of the contact thermal resistance ( C + S) is changed by insulating sheet (mica) and heat sink grease. TABLE 1. UNIT: /W PACKAGE MODEL NO. TORQUE TO-220AB KIA78xxAP 6kg cm (0.6N/m) Not Provided C+ S 0.3 0.5(1.5 2.0) Provided 2.0 2.5(4.0 6.0) MICA The figures given in parentheses denote the values at time of no grease. The package of regulator IC serves as GND, therefore, usually use the value at time of "no mica" (b) Silicon grease When a circuit not exceeding maximum rating is designed, it is to be desired that the grease should be used if possible. If it is required that the contact thermal resistance is reduced from the view-point of the circuit design, It is recommended that the following methods be adopted. A: Use Thercon (Fuji High Polymer Kogyo K.K) B: Use SC101 (Torei Silicon) or G-640 (GE), if grease is used. (c) Torque When installing IC on a heat sink or the like, tighten the IC with the torque of less than the rated value. If it is tightened with the torque in excess of the rated value, sometimes the internal elements of the IC are adversely affected. Therefore, great care should be given to the installing operation. Further, if polycarbonate screws are used, the torque causes a change with the passage of time, which may lessen the effect of radiation. 2010. 5. 19 Revision No : 1 17/20 KIA7805AP~KIA7824AP (6) IEC (International Electronical Commission)-65 Specification.
