BDxxGA3WEFJ / BDxxGA3WNUX  
General Description  
BDxxGA3WEFJ / BDxxGA3WNUX series devices are LDO regulators with output current capability of 0.3A. It has an output  
voltage accuracy of ±1%. Both fixed and variable output voltage devices are available. The variable output voltage can be  
varied from 1.5V to 13.0V using external resistors. Various fixed output voltage devices that do not use external resistors  
are also available. These LDO regulators are available in HTSOP-J8 / VSON008X2030 package and can be used in wide  
variety of digital appliances. It has built-in over current protection to protect the device when output is shorted, 0μA  
shutdown mode, and thermal shutdown circuit to protect the device during thermal over-load conditions. These LDO  
regulators are usable with ceramic capacitors that enable a smaller layout and longer life.

As the power consumption increases above the maximum allowable power dissipation of the chip, the temperature across  
the chip also increases. When considering thermal design for the regulator, operation should be maintained within the  
following conditions:  
1. Ambient temperature Ta can be not higher than 85.  
2. Chip junction temperature (Tj) can be not higher than 150.  
Chip junction temperature can be determined as follows:

Most of the heat loss that occurs in the BDxxGA3WEFJ / BDxxGA3WNUX series is generated from the output Pch FET.  
Power loss is determined by the voltage drop across VCC-VO and the output current. Be sure to confirm the system’s input  
and output voltages, as well as the output current conditions in relation to the power dissipation characteristics of the VCC  
and VO in the design. Bearing in mind that the power dissipation may vary substantially depending on the PCB employed, it  
is important to consider PCB size based on thermal design and power dissipation characteristics of the chip with the PCB.  
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 and Output Capacitor  
It is recommended that a capacitor is placed near pins between input pin and GND as well as output pin and GND. The  
input capacitor becomes more necessary when the power supply impedance is high or when the PCB trace has significant  
length. Also, as for a capacitor between output pin and GND, the greater the capacitance, the more stable the output will  
be depending on the load and line voltage variations. However, please check the actual functionality of this part by  
mounting on a board for the actual application. Ceramic capacitors usually have different thermal and equivalent series  
resistance characteristics and may degrade gradually over continued use.  
For additional details, please check with the manufacturer and select the best ceramic capacitor for your application.

Equivalent Series Resistance ESR (ceramic capacitor etc.)  
To prevent oscillation, please attach a capacitor between VO  
and GND. Capacitors usually have ESR (Equivalent Series  
Resistance). Operation will be stable in ESR-IO range shown in  
the right. Ceramic, tantalum and electronic capacitors have  
different ESR values, so please be sure to use a capacitor that  
operates in the stable operating region shown in the right.  
Finally, please evaluate in the actual application.

Input capacitor CIN connected to VCC (VIN) should be placed as close as possible to VCC(VIN) pin and use wide layout.  
Output capacitor COUT should also be placed as close as possible to IC pin. In case connected to inner layer GND plane,  
please use several through hole.  
FB pin has comparatively high impedance and can be affected by noise, so floating capacitance should be small as  
possible. Please be careful of this during layout.  
Please make GND pattern wide enough to handle the power dissipation of the chip.  
For output voltage setting (BD00GA3WEFJ / BD00GA3WNUX)  
Output voltage can be set by FB pin voltage0.800V typ.and external resistance R1, R2.

Operational Notes  
(1). Absolute maximum ratings  
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit  
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such  
as adding a fuse, in case the IC is operated over the absolute maximum ratings.  
(2). Reverse connection of power supply  
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when  
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power  
supply terminals.  
(3). Power supply lines  
Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply  
lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting  
the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of  
temperature and aging on the capacitance value when using electrolytic capacitors.  
(4). Ground voltage  
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that  
no pins are at a voltage below the ground pin at any time, even during transient condition.  
(5). Thermal consideration  
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd)  
in actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (PcPd)  
Package Power dissipation  
Power dissipation  
: Pd (W)=(TjmaxTa)/θja  
: Pc (W)=(VccVo)×Io+Vcc×Ib  
Tjmax : Maximum junction temperature=150, Ta : Peripheral temperature[] ,  
θja : Thermal resistance of package-ambience[/W], Pd : Package Power dissipation [W],  
Pc : Power dissipation [W], Vcc : Input Voltage, Vo : Output Voltage, Io : Load, Ib : Bias Current  
(6). Short between pins and mounting errors  
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong  
orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the  
pins.  
(7). Operation under strong electromagnetic field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.  
(8). Area of Safe Operation (ASO)  
Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe  
Operation (ASO).  
(9). Thermal shutdown circuit  
The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal  
temperature of the IC reaches a specified value. It is not designed to protect the IC from damage or guarantee its  
operation. Do not continue to operate the IC after this function is activated. Do not use the IC in conditions where this  
function will always be activated.

(10). Testing on application boards  
175  
15  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may  
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply  
should always be turned off completely before connecting or removing it from the test setup during the inspection

process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during  
transport and storage.  
(11). Regarding input pins 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 the P layers with the N layers of other elements, creating a  
parasitic diode or transistor. For example (refer to figure below):  
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 inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual  
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to  
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should  
be avoided.

(12). Ground Wiring Pattern.  
When using both small-signal and large-current ground traces, the two ground traces should be routed separately  
but connected to a single ground at the reference point of the application board to avoid fluctuations in the  
small-signal ground caused by large currents. Also ensure that the ground traces of external components do not  
cause variations on the ground voltage. The power supply and ground lines must be as short and thick as possible to  
reduce line impedance.
