1A Variable / Fixed Output
LDO Regulator
BDxxGC0WEFJ
●General Description
BDxxGC0WEFJ is a LDO regulator with output current 1.0A. The output accuracy is ±1% of output voltage. With external
resistance, it is available to set the output voltage at random (from 1.5V to 13.0V) and also provides output voltage fixed
type without external resistance. It is used for the wide applications of digital appliances. It has package type: HTSOP-J8.
Over current protection (for protecting the IC destruction by output short circuit), circuit current ON/OFF switch (for setting
the circuit 0μA at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load
condition) are all built in. It is usable for ceramic capacitor and enables to improve smaller set and long-life.

Most of the heat loss that occurs in the BDxxGC0WEFJ 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 BDxxGC0WEFJ 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] = 5.0 V - 3.3V ×0.1A
=0.17[W]

●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(BD00GC0WEFJ)
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.

notice. Before purchasing or using ROHM’s Products, please confirm the latest information with a ROHM sales
representative.
●Precaution on using ROHM Products
1) Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you
intend to use our Products in devices requiring extremely high reliability (such as medical equipment, transport
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific
Applications.
2) ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3) Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of

residue after soldering
[h] Use of the Products in places subject to dew condensation
4) The Products are not subject to radiation-proof design.
5) Please verify and confirm characteristics of the final or mounted products in using the Products.
6) In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse) is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7) De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8) Confirm that operation temperature is within the specified range described in the product specification.
