Substrate size: 70mm×70mm×1.6mm (substrate with thermal via)
Most of the heat loss that occurs in the BDxxHA5MEFJ-LB is generated from the output Pch FET. Power loss is determined
by the total VCC-VO voltage and output current. Be sure to confirm the system input and output voltage and the output
current conditions in relation to the heat dissipation characteristics of the VCC and VO in the design. Bearing in mind that
heat dissipation may vary substantially depending on the substrate employed (due to the power package incorporated in
the BDxxHA5MEFJ-LB make certain to factor conditions such as substrate size into the thermal design.
Power consumption[W] = Input voltage (VCC) - Output voltage (VO) ×IO(Ave)
Example) Where VCC=5.0V, VO=3.3V, IO(Ave) = 0.1A,
Power consumption[W] = 5.0V - 3.3V ×0.1A
=0.17W

Input-to-Output Capacitor
It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND.
A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for
a capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes
improvement of characteristics by load change. However, please check by mounted on a board for the actual application.
Ceramic capacitor usually has difference, thermal characteristics and series bias characteristics, and moreover capacity
decreases gradually by using conditions.
For more detail, please be sure to inquire the manufacturer, and select the best ceramic capacitor.

･Input capacitor CIN of VCC (VIN) should be placed very close to VCC(VIN) pin as possible, and used broad wiring pattern.
Output capacitor COUT also should be placed close to IC pin as possible. In case connected to inner layer GND plane,
please use several through hole.
・FB pin has comparatively high impedance, and is apt to be effected by noise, so floating capacity should be minimum as
possible. Please be careful in wiring drawing
・Please take GND pattern space widely, and design layout to be able to increase radiation efficiency.
・For output voltage setting
Output voltage can be set by FB pin voltage（0.800V typ.）and external resistance R1, R2.

Operational Notes
(1). Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,
can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open
circuit. If any over rated values will expect to exceed the absolute maximum ratings, 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 IC. Take precautions when connecting the power
supply lines. An external direction diode can be added.
(3). Power supply lines
Design 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 the GND terminal. When applying electrolytic
capacitors in the circuit, not that capacitance characteristic values are reduced at low temperatures.
(4). GND voltage
The potential of GND pin must be minimum potential in 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.

(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.

(11). 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.

(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.
