A capacitor, between input pin and GND, is valid when the power supply impedance is high or trace is long. Also, as for the capacitor between the output pin and GND, the greater the capacitance, the more sustainable the line regulation will be and the capacitor will make improvements of characteristics depending on the load. However, please check the actual functionality of this part by mounting it on a board for the actual application. Ceramic capacitors usually have different, thermal and equivalent series resistance characteristics, and moreover capacitance decreases gradually in use. For additional details, please check with the manufacturer, and select the best ceramic capacitor for your application. 10 Rated Voltage：10V B1 characteristics Rated Voltage：10V B characteristics 0 Capacitance Change [%] -10 Rated Voltage：6.3V B characteristics -20 -30 -40 -50 Rated Voltage:10V F characteristics -60 Rated Voltage：4V X6S characteristics -70 -80 -90 -100 0 1 2 3 4 DC Bias Voltage [V] Ceramic capacitor capacity – DC bias characteristics (Characteristics example) ●Equivalent Series Resistance ESR (ceramic capacitor etc.) 10.00 1.00 Safety Area ESR [Ω] To prevent oscillations, please attach a capacitor between VO and GND.

Output capacitor COUT also should be placed as close to IC pin as possible. In case the part is connected to inner layer GND plane, please use several through holes. ・FB pin has comparatively high impedance and can be affected by noise, so stray capacitance should be as small as possible. Please take care of this during layout. ・Please make GND pattern wide enough to handle thermal dissipation. ・For output voltage setting (BD00GA5WEFJ) Output voltage can be set by FB pin voltage（0.800V typ.）and external resistance R1, R2.

If there is any possibility of exposure over the rated values, please consider adding circuit protection devices such as fuses. (2) Connecting the power supply connector backward Connecting of the power supply in reverse polarity can damage the IC. Take precautions when connecting the power supply lines. An external direction diode can be added. (3) Power supply lines Design the PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply terminals to ICs, connect a capacitor between the power supply and GND terminal. When using electrolytic capacitors in a circuit, note that capacitance values are reduced at low temperatures and over time. (4) GND voltage The potential of the GND pin must be minimum potential under all operating conditions. (5) Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. (6). Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. (7). Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. (8). ASO When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO. (9). Thermal shutdown circuit The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is assumed. BDxxGA5WEFJ TSD ON Temperature[℃] (typ.) 175 Hysteresis Temperature [℃] 15 (typ.) (10). Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

Regarding input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated.P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used. Resistor Transistor (NPN) Pin A Pin B C B Pin B E Pin A N N P + N P P + N P + P Parasitic element P substrate Parasitic element GND B N P N P substrate Parasitic element GND C + GND E Parasitic element Other adjacent elements GND (12). Ground Wiring Pattern. When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.
