TECHNICAL NOTE

3-terminal Regulator ＆ LDO Regulator Series

Standard Fixed Output

LDO Regulator

BA□□DD0,BA□□DD0W,BA□□CC0 and BA□□CC0W Series

●General Description

BA□□DD0/CC0 are low-saturation regulators, available for output s up to 2A/1A. ROHM has a wide output voltage range

and package lineup with and without shutdown switches. This IC has a built-in over-current protection circuit that prevents

the destruction of the IC due to output short circuits, a thermal shut-down circuit that protects the IC from damage due to

overloading and an over-voltage protection circuit that protects the IC from surges generated in the power supply line of the

IC.

●Features

1) Maximum output current : 2A (BA□□DD0),

1A(BA□□CC0)

5) Built-in thermal shutdown circuit for protecting the

IC from damage due to overloading

2) ±1% highly accurate output voltage (BA□□DD0)

3) Low saturation with PNP output

4) Built-in over-current protection circuit that prevents

the destruction of the IC due to output short circuits

6) Built-in over- voltage protection circuit that prevents

the destruction of the IC due to power supply

surges

7) TO220FP and HRP5 packaging (BA□□DD0)

TO220FP and TO252 packaging(BA□□CC0)

Ambient temperature:Ta(℃）

Fig.31

When using at temperatures over Ta=25℃, please refer to the heat reducing characteristics shown in Fig.29 through 31. The IC

characteristics are closely related to the temperature at which the IC is used and if the temperature exceeds the maximum

junction temperature TjMAX., the elements may be damaged or destroyed. From the standpoints of instantaneous destruction and

long-term operating reliability, it is necessary give sufficient consideration to IC heat. In order to protect the IC from thermal

damage, it is necessary to operate it at temperatures lower than the maximum junction temperature TjMAX of the IC.

5/8

Fig.30 shows the acceptable loss and heat reducing characteristics of the TO220FP package The portion shown by the

diagonal line is the acceptable loss range that can be used with the IC alone. 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.

Circuit current

The method of calculating the power consumption Pc(W) is as follows.

Pc = (Vcc-Vo) × Io ＋ Vcc × Icca

Acceptable loss Pd≦Pc

Icca：

Solving this for load current IO in order to operate within the acceptable loss:

Pd – Vcc×Icca

Io≦

Vcc－Vo

（Please refer to Figs.8 and 20 for Icca.）

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=8.3V, Vo=3.3V, BA33DD0WT

1.04－8.3×Icca

Io≦

With the IC alone : θja=62.5℃/W → -16mW/℃

25℃=2000mW → 85℃=1040mW

Io≦200mA (Icca : 2mA)

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

●Peripheral Circuit Considerations

・Vcc Terminal

Please attach a capacitor (greater than 0.33μF) between the Vcc and GND.

The capacitance values will differ depending on the application, so please take this into account when configuring the

terminal.

・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 outputted, causing

the system to become unstable. Therefore, please reduce the impedance by making the ground patterns as wide as

possible and by 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.

The power supply and the CTL terminal may be started up and shut down in any order without problems.

(BA□□CC0,22μF)

（BA□□DD0,22μF）

Please attach an anti-oscillation capacitor between Vcc and GND. The capacitance of the capacitor may significantly change

due to factors such as temperature changes, making it impossible to completely stop oscillations. Please use a tantalum

capacitor or aluminum electrolysis capacitor with favorable characteristics and small internal series resistance (ESR) even at

low temperatures. The output fluctuates regardless of whether the ESR is large or small. Please use the IC within the stable

operating region while referring to the ESR characteristics reference data shown in Figs.32 through 34. In applications where

there are sudden load fluctuations, the use of a capacitor with large capacitance is recommended.

Below figure , it is ESR-to-Io stability Area characteristics ,measured by 22μＦ-ceramic-capacitor and resistor connected in

series.

This characteristics is not equal value perfectly to 22μＦ-aluminum electrolytic capacitor in order to measurement

method.

Note, however, that the stable range suggested in the figure depends on the IC and the resistance load involved, and can vary

with the board’s wiring impedance, input impedance, and/or load impedance. Therefore, be certain to ascertain the final status

of these items for actual use.

Keep capacitor capacitance within a range of 22μF～1000μF. It is also recommended that a 0.33μF bypass capacitor be

connected as close to the input pin-GND as location possible. However, in situations such as rapid fluctuation of the input

voltage or the load, please check the operation in real application to determine proper capacitance.

Other Points of Caution

1)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 overcurrent

protection circuit has negative current capacity characteristics with regard to temperature (Refer to Figs.4 and 16).

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

above, this must be used within the range of acceptable loss, but if the acceptable loss happens to be continuously exceeded,

the chip temperature Tj increases, causing the temperature protection 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 Figs.12

and 24 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.35).

2) This IC is bipolar IC that has a P-board (substrate) and P+ isolation layer

between each devise, as shown in Fig.36. A P-N junction is formed between

Reverse current

this P-layer and the N-layer of each device, and the P-N junction operates as a

parasitic diode when the electric potential relationship is GND> Terminal A,

OUT

Vcc

GND> Terminal B, while it operates as a parasitic transistor when the electric

potential relationship is Terminal B GND> Terminal A. Parasitic devices are

structurally inevitable in the IC. The operation of parasitic devices induces

mutual interference between circuits, causing malfunctions and eventually the

destruction of the IC. It is necessary to be careful 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.
