The IC characteristics are closely related to the temperature at which the IC is used and if the temperature exceeds the maximum junction temperature TjMAX., the elements may be damaged or destroyed. From the standpoints of instantaneous destruction and long-term operating reliability, it is necessary give sufficient consideration to IC heat. In order to protect the IC from thermal damage, it is necessary to operate it at temperatures lower than the maximum junction temperature TjMAX of the IC. Fig.30 shows the acceptable loss and heat reducing characteristics of the TO220FP package The portion shown by the diagonal line is the acceptable loss range that can be used with the IC alone. Even when the ambient temperature Ta is a normal temperature (25℃), the chip (junction) temperature Tj may be quite high so please operate the IC at temperatures less than the acceptable loss Pd. The method of calculating the power consumption Pc(W) is as follows. Pc = (Vcc-Vo) × Io ＋ Vcc × Icca Acceptable loss Pd≦Pc Vcc：Input voltage Vo：Output voltage Io：Load current Vcca：Circuit current Solving this for load current IO in order to operate within the acceptable loss: Io≦ Pd – Vcc×Icca Vcc－Vo (Please refer to Figs.8 and 20 for Icca.) It is then possible to find the maximum load current IoMAX with respect to the applied voltage Vcc at the time of thermal design. ・Calculation Example Example 1) When Ta=85℃, Vcc=8.3V, Vo=3.3V, BA33DD0WT 1.04－8.3×Icca Io≦ With the IC alone : θja=62.5℃/W → -16mW/℃ 5 Io≦200mA (Icca : 2mA) 25℃=2000mW → 85℃=1040mW Please refer to the above information and keep thermal designs within the scope of acceptable loss for all operating temperature ranges. The power consumption Pc of the IC when there is a short circuit (short between Vo and GND) is : Pc=Vcc×(Icca＋Ishort) *Ishort : Short circuit current ●Peripheral Circuit Considerations ・Vcc Terminal Please attach a capacitor (greater than 0.33μF) between the Vcc and GND. The capacitance values will differ depending on the application, so please take this into account when configuring the terminal. ・GND Terminal Please be sure to keep the set ground and IC ground at the same potential level so that a potential difference does not arise between them. If a potential difference arises between the set ground and the IC ground, the preset voltage will not be outputted, causing the system to become unstable. Therefore, please reduce the impedance by making the ground patterns as wide as possible and by reducing the distance between the set ground and the IC ground as much as possible. ・CTL Terminal The CTL terminal is turned ON at 2.0V and higher and OFF at 0.8V and lower within the operating power supply voltage range. The power supply and the CTL terminal may be started up and shut down in any order without problems. www.rohm.com © 2010 ROHM Co., Ltd.

The capacitance of the capacitor may significantly change due to factors such as temperature changes, making it impossible to completely stop oscillations. Please use a tantalum capacitor or aluminum electrolysis capacitor with favorable characteristics and small internal series resistance (ESR) even at low temperatures. The output fluctuates regardless of whether the ESR is large or small. Please use the IC within the stable operating region while referring to the ESR characteristics reference data shown in Figs.32 through 34. In applications where there are sudden load fluctuations, the use of a capacitor with large capacitance is recommended. ●Other Points of Caution 1)Protection Circuits Over-current Protection Circuit A built-in over-current protection circuit corresponding to the current capacity prevents the destruction of the IC when there are load shorts. This protection circuit is a “7”-shaped current control circuit that is designed such that the current is restricted and does not latch even when a large current momentarily flows through the system with a high-capacitance capacitor. However, while this protection circuit is effective for the prevention of destruction due to unexpected accidents, it is not suitable for continuous operation or transient use. Please be aware when creating thermal designs that the overcurrent protection circuit has negative current capacity characteristics with regard to temperature (Refer to Figs.4 and 16). Thermal Shutdown Circuit (Thermal Protection) This system has a built-in temperature protection circuit for the purpose of protecting the IC from thermal damage. As shown above, this must be used within the range of acceptable loss, but if the acceptable loss happens to be continuously exceeded, the chip temperature Tj increases, causing the temperature protection circuit to operate. When the thermal shutdown circuit operates, the operation of the circuit is suspended. The circuit resumes operation immediately after the chip temperature Tj decreases, so the output repeats the ON and OFF states (Please refer to Figs.12 and 24 for the temperatures at which the temperature protection circuit operates). There are cases in which the IC is destroyed due to thermal runaway when it is left in the overloaded state. Be sure to avoid leaving the IC in the overloaded state. Reverse Current In order to prevent the destruction of the IC when a reverse current flows through the IC, it is recommended that a diode be placed between the Vcc and Vo and a pathway be created so that the current can escape (Refer to Fig.35). 2) This IC is bipolar IC that has a P-board (substrate) and P+ isolation layer between each devise, as shown in Fig.36. A P-N junction is formed between this P-layer and the N-layer of each device, and the P-N junction operates as a parasitic diode when the electric potential relationship is GND> Terminal A, GND> Terminal B, while it operates as a parasitic transistor when the electric potential relationship is Terminal B GND> Terminal A. Parasitic devices are structurally inevitable in the IC. The operation of parasitic devices induces mutual interference between circuits, causing malfunctions and eventually the destruction of the IC. It is necessary to be careful not to use the IC in ways that would cause parasitic elements to operate. For example, applying a voltage that is lower than the GND (P-board) to the input terminal.
