500mA Variable/Fixed Output
LDO Regulators
BDxxKA5 Series BDxxKA5W Series BD00KA5W Series
●General Description
The BDxxKA5 series are low-saturation regulators that are available for output currents up to 500mA. The output voltage
precision is ±1%. These LDO regulators are offered in several output voltages and package lineups with or without
ON/OFF switches (that set the circuit current to 0μA at shutdown). This series can be used for a broad spectrum of
applications ranging from TVs and car audio systems to HDDs, PCs, and DVDs. There regulators have a built-in
overcurrent protection circuit that prevents the destruction of the IC, due to output short circuits and a thermal shutdown
circuit.

When using at temperatures over Ta=25℃, please refer to the power dissipation shown in Fig.20 through 22.
The IC characteristics are closely related to the temperature at which the IC is used, so if the temperature exceeds the
maximum junction temperature TjMAX, the device may malfunction or be destroyed. The heat of the IC requires sufficient
consideration regarding instantaneous destruction and long-term operation reliability. In order to protect the IC from thermal
damage, it is necessary to operate it at temperatures less than the maximum junction temperature TjMAX.
Even when the ambient temperature Ta is a normal temperature (25℃), the chip(junction) temperature Tj may be quite high,
so please operate the IC at temperatures less than the acceptable loss Pd.

The calculation method for power consumption Pc(W) is as follows :
Vcc：
Vo：
Input voltage
Output voltage
Load current
Circuit current
Pc = (Vcc-Vo)×Io+Vcc×Icca
Acceptable loss Pd≧Pc
Io：
Icca：
Solving for the load current IO in order to operate within the acceptable loss,
Pc – Vcc×Icca
Io≦
Vcc－Vo
It is then possible to find the maximum load current IoMAX with respect to the applied voltage Vcc at the time of thermal design.
Calculation Example
Example 1) When Ta=85℃, Vcc=2.5V, Vo=1.0V
BA10KA5WFP（TO252-5 packaging）
0.676－2.5×Icca
Io≦
Io≦440mA (Icca : 6mA)
θja=96.2℃/W → -10.4mW/℃
2.5-1.0
25℃=1300mW → 85℃=676mW
Please refer to the above information and keep thermal designs within the scope of acceptable loss for all operating
temperature ranges.
The power consumption Pc of the IC when there is a short circuit (short between Vo and GND) is :
Pc=Vcc×(Icca+Ishort)
*Ishort : Short circuit current
●Terminal Vicinity Settings and Cautions
・Vcc Terminal
Please attach a capacitor (greater than 1μF) between Vcc and GND.
The capacitance values differ depending on the application, so chose a capacitor with sufficient margin and verify the
operation on actual board.
・GND Terminal
Please be sure to keep the set ground and IC ground at the same potential level so that a potential difference does not
arise between them. If a potential difference arises between the set ground and the IC ground, the preset voltage will not
be output properly, causing the system to become unstable. Please reduce the impedance by making the ground patterns
as wide as possible and reducing the distance between the set ground and the IC ground as much as possible.
・CTL Terminal
The CTL terminal is turned ON at 2.0V and higher, and OFF at
0.8V and lower, within the operating power supply voltage range.
31.25kΩ
CTL
The power supply and the CTL terminal may be started up and
shut down in any order without problems.

Be sure to place an anti-oscillation capacitor between the output terminal and the GND. Oscillations may arise if the
capacitance value changes, due to factors such as temperature changes. A 1μF capacitor with small internal series resistance
(ESR) such as a ceramic capacitor is recommended as an anti-oscillation capacitor. Ceramic capacitors generally have
favorable temperature characteristics and DC bypass characteristics. When selecting a ceramic capacitor, a high voltage
capacitor (good DC bypass characteristics) with temperature characteristics that are superior to those of X5R or X7R, is
recommended. In applications where input voltage and load fluctuations are rapid, please decide on a capacitor after
sufficiently confirming its properties according to its specifications in the actual application.

●Operational Notes
○Protection Circuits
Over-current Protection Circuit
A built-in over-current protection circuit corresponding to the current capacity prevents the destruction of the IC when
there are load shorts. This protection circuit is a “7”-shaped current control circuit that is designed such that the current is
restricted and does not latch even when a large current momentarily flows through the system with a high-capacitance
capacitor. However, while this protection circuit is effective for the prevention of destruction due to unexpected accidents,
it is not suitable for continuous operation or transient use. Please be aware when creating thermal designs that the
over-current protection circuit has negative current capacity characteristics with regard to temperature.
○Thermal Shutdown Circuit (Thermal Protection)
This system has a built-in temperature protection circuit for the purpose of protecting the IC from thermal damage. As
shown in Fig. 20-22, this must be used within the range of acceptable loss, but if the acceptable loss is continuously
exceeded, the chip temperature Tj increases, causing the thermal shutdown circuit to operate. When the thermal shutdown
circuit operates, the operation of the circuit is suspended. The circuit resumes operation immediately after the chip
temperature Tj decreases, so the output repeats the ON and OFF states (Please refer to Fig.17 for the temperatures at
which the temperature protection circuit operates).
There are cases in which the IC is destroyed due to thermal runaway when it is left in the overloaded state. Be sure to
avoid leaving the IC in the overloaded state.
○Reverse Current
In order to prevent the destruction of the IC when a reverse current flows through the IC, it is recommended that a diode
be placed between the Vcc and Vo and a pathway be created so that the current can escape (Refer to Fig.27).

Vcc

CTL
GND
Fig.27 Bypass diode
○This IC is BI-CMOS IC that has a P-board (substrate) and P+ isolation between each element, as shown in Fig.28. A P-N
junction is formed between this P-layer and the N-layer of each element, and the P-N junction operates as :
- a parasitic diode when the electric potential relationship is GND> Pin A, GND> Pin B, or
- a parasitic transistor when the electric potential relationship is Pin B > GND> Pin A.
Parasitic elements are structurally inevitable in the IC. The operation of parasitic elements induces mutual interference
between circuits, causing malfunctions and eventually the destruction of the IC. Take precaution as not to use the IC in
ways that would cause parasitic elements to operate. For example, applying a voltage that is lower than the GND (P-board)
to the input terminal.

Notice
●General Precaution
1) Before you use our Products, you are requested to carefully read this document and fully understand its contents.
ROHM shall not be in any way responsible or liable for failure, malfunction or accident arising from the use of any
ROHM’s Products against warning, caution or note contained in this document.
2) All information contained in this document is current as of the issuing date and subject to change without any prior
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
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
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.
9) ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
