The capacitor between the input terminal and GND becomes valid when source impedance increases or when wiring is long. The larger the capacity of the output capacitor between the output terminal and GND is, the better the stability and characteristics in output load fluctuation become. However, please check the status of actual implementation. Ceramic capacitors generally have variation, temperature characteristics, and direct current bias characteristics and the capacity value also decreases with time depending on the usage conditions. It is recommended to select a ceramic capacitor upon inquiring about detailed data of the related manufacturer. 10-V withstand voltage B characteristics -20 6.3-V withstand voltage B characteristics -30 10-V withstand voltage F characteristics -40 -50 -60 4-V withstand voltage X6S characteristics 10-V withstand voltage F characteristics -70 -80 -90 -100 0 0.5 1 1.5 2 2.5 3 3.5 4 DC Bias Voltage [V] Fig.3 Capacity - bias characteristics About the equivalent series resistance (ESR) of a ceramic capacitor Cout=0.47F ,CIN=0.47F ,Temp=+25 100 Unstable region 10 ESR[] [] ESR Capacitors generally have ESR (equivalent series resistance) and it operates stably in the ESR-IOUT area shown on the right.

VIN Response 37/41 2011.01 - Rev.B Technical Note BUTD2WNVX series About power dissipation (Pd) As for power dissipation, an approximate estimate of the heat reduction characteristics and internal power consumption of IC are shown, so please use these for reference. Since power dissipation changes substantially depending on the implementation conditions (board size, board thickness, metal wiring rate, number of layers and through holes, etc.), it is recommended to measure Pd on a set board. Exceeding the power dissipation of IC may lead to deterioration of the original IC performance, such as causing operation of the thermal shutdown circuit or reduction in current capability. Therefore, be sure to prepare sufficient margin within power dissipation for usage. Calculation of the maximum internal power consumption of IC (PMAX) PMAX=(VIN-VOUT)xIOUT(MAX.)

All rights reserved. 39/41 2011.01 - Rev.B Technical Note BUTD2WNVX series Notes for use 1) About absolute maximum rating Breakage may occur when absolute maximum ratings such as applied voltage and operating temperature range are exceeded. Short mode or open mode cannot be specified at occurrence of a break, so please prepare physical safety measures (e.g., fuse) if such special mode in which the absolute maximum rating is exceeded can be assumed. 2) About GND potential Please be sure that the potential of the GND terminal is the lowest in any operating condition. 3) About thermal design Please provide thermal design with sufficient margin, taking power dissipation (Pd) in actual usage conditions into consideration. 4) About short between pins and misattachment Please be careful regarding the IC direction and misalignment at attachment onto a printed circuit board. Misattachment may cause a break of IC. Short caused by foreign matter between outputs, output and power supply, or GNDs may also lead to a break. 5) About operation in a strong electromagnetic field Please note that usage in a strong electromagnetic field may cause malfunction. 6) About common impedance Please give due consideration to wiring of the power source and GND by reducing common-mode ripple or making ripple as small as possible (e.g., making the wiring as thick and short as possible, or reducing ripple by LC), etc. 7) About STBY terminal voltage Set STBY terminal voltage to 0.3 V or less to put each channel into a standby state and to 1.2 V or more to put each channel into an operating state. Do not fix STBY terminal voltage to 0.3 V or more and 1.2 V or less or do not lengthen the transition time. This may cause malfunction or failure. When shorting the VIN terminal and STBY terminal for usage, the status will be "STBY=VIN=LOW" at turning the power OFF, and discharge of the VOUT terminal cannot operate, which means voltage may remain for a certain time in the VOUT terminal. Since turning the power ON again in this state may cause overshoot, turn the power ON for use after the VOUT terminal is completely discharged. 8) About overcurrent protection circuit Output has a built-in overcurrent protection circuit, which prevents IC break at load short. Note that this protection circuit is effective for prevention of breaks due to unexpected accidents. Please avoid usage by which the protection circuit operates continuously. 9) About thermal shutdown Output is OFF when the thermal circuit operates since a temperature protection circuit is built in to prevent thermal breakdown. However, it recovers when the temperature returns to a certain temperature. The thermal circuit operates at emergency such as overheating of IC. Since it is prepared to prevent IC breakdown, please do not use it in a state in which protection works. Reverse current About reverse current For applications on which reverse current is assumed to flow into IC, it is recommended to prepare a path to let the current out putting a bypass diode between the VIN-VOUT terminals. VIN STBY OUT by GND Fig. 289. Example of bypass diode connection About testing on a set board When connecting a capacitor to a terminal with low impedance for testing on a set board, please be sure to discharge for each process since IC may be stressed. As a countermeasure against static electricity, prepare grounding in the assembly process and take sufficient care in transportation and storage. In addition, when connecting a capacitor to a jig in a testing process, please do so after turning the power OFF and remove it after turning the power OFF. www.rohm.com (c) 2011 ROHM Co., Ltd.
