BA78□□Series,BA78M□□Series Technical Note ●Thermal design Refer to the following thermal derating curves (Fig. 25, 26), when using in the status of Ta=25℃ or more. The characteristic of IC is greatly related to the operating temperature. When it is used in over maximum junction temperature, the elements inside IC might become weaker and be destroyed. It is recommended to take into consideration thermal of IC. Note that the temperatures are in the allowed temperature limits and operated within Pd. It is necessary to operate it at junction temperature Tjmax or less to prevent IC from the thermal destruction. Please operate IC within permissible loss Pd because the junction temperature Tj might become considerably a high temperature even if ambient temperature Ta is normal temperature (25℃). Power consumption Pc(W) may be expressed by the equation shown below: Pc=(Vin-Vo)×Io+ Vin×Ib Vin : Input Voltage permissible loss Pd≧Pc Vo : Output Voltage Io : Output Current PdVinIb Io≦ Ib : Bias current VinVo Maximum Output current Io can be calculated in thermal design.

The value of capacitor is designed suitable for the actual application. ・OUTPUT It is recommended that a capacitor (about 0.1uF) be inserted between OUTPUT and COMMON. A tantalum capacitor can also be used for this pin because insufficient capacitors may cause oscillation by a temperature change. ・COMMON Keep the no voltage drop between Ground level of set board and IC. When there is the voltage difference, setting voltage becomes inaccuracy and unstable. It is recommended to connect by wide, short pattern, and lower the inpedance. www.rohm.com 10/12 2012.03 - Rev.C © 2012 ROHM Co., Ltd. All rights reserved.

BA78□□Series,BA78M□□Series Technical Note ●Notes for use (1) Absolute Maximum Ratings While utmost care is taken to quality control of this product, any application that may exceed some of the absolute maximum ratings including the voltage applied and the operating temperature range may result in breakage. If broken, short-mode or open-mode may not be identified. So if it is expected to encounter with special mode that may exceed the absolute maximum ratings, it is requested to take necessary safety measures physically including insertion of fuses. (2) Ground voltage Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric transient. (3) Thermal design When you do the kind of use which exceeds Pd, It may be happened to deteriorating IC original quality such as decrease of electric current ability with chip temperature rise. Do not exceed the power dissipation (Pd) of the package specification rating under actual operation, and please design enough temperature margins. (4) Short-circuiting between terminals, and mismounting When mounting to pc board, care must be taken to avoid mistake in its orientation and alignment. Failure to do so may result in IC breakdown. Short-circuiting due to foreign matters entered between output terminals, or between output and power supply or GND may also cause breakdown. (5) Operation in Strong electromagnetic field Be noted that using the IC in the strong electromagnetic radiation can cause operation failures. (6) Inspection with the IC set to a pc board If a capacitor must be connected to the pin of lower impedance during inspection with the IC set to a pc board, the capacitor must be discharged after each process to avoid stress to the IC. For electrostatic protection, provide proper grounding to assembling processes with special care taken in handling and storage. When connecting to jigs in the inspection process, be sure to turn OFF the power supply before it is connected and removed. (7) Input to IC terminals This is a monolithic IC with P+ isolation between P-substrate and each element as illustrated below. This P-layer and the N-layer of each element form a P-N junction, and various parasitic element are formed. If a resistor is joined to a transistor terminal as shown in Fig 28. ○P-N junction works as a parasitic diode if the following relationship is satisfied; GND>Terminal A (at resistor side), or GND>Terminal B (at transistor side); and ○if GND>Terminal B (at NPN transistor side), a parasitic NPN transistor is activated by N-layer of other element adjacent to the above-mentioned parasitic diode. The structure of the IC inevitably forms parasitic elements, the activation of which may cause interference among circuits, and/or malfunctions contributing to breakdown. It is therefore requested to take care not to use the device in such manner that the voltage lower than GND (at P-substrate) may be applied to the input terminal, which may result in activation of parasitic elements. (8) Ground wiring pattern If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay attention not to cause fluctuations in the GND wiring pattern of external parts as well. (9) Thermal shutdown circuit A temperature control circuit is built in the IC to prevent the damage due to overheat.Therefore, the output is turned off when the thermal circuit works and is turned on when the temperature goes down to the specified level. But, built-in the IC a temperature control circuit to protect itself, and avoid the design used the thermal protection. (10) Over current protection circuit The over-current protection circuits are built in at output, according to their respective current outputs and prevent the IC from being damaged when the load is short-circuited or over-current. But, these protection circuits are effective for preventing destruction by unexpected accident. When it’s in continuous protection circuit moving period don’t use please. And for ability, because this chip has minus characteristic, be careful for heat plan. (11) There is a possibility to damage an internal circuit or the element when Vin and the voltage of each terminal reverse in the application. For instance, Vin is short-circuited to GND etc. with the charge charged to an external capacitor. Please use the capacitor of the output terminal with 1000μF or less. Moreover, the Vin series is recommended to insert the diode of the by-pass the diode of the backflow prevention or between each terminal and Vin.
