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 T jMAX., the elements may be damaged or destroyed. Fr om the standpoints of instantaneous
destruction and long-term operating rel iability, it is necessary give s ufficient consideration to IC heat. In order to protect the
IC from thermal damage, it is necessary to operate it at temperatures lo we r than the maximum junction temperature TjMAX
of the IC.
Fig.30 shows the acceptable loss and heat reducing characteristics of the TO220FP package The portion shown by the
diagonal line is the acceptabl e loss range that can be used with the IC alone. Even when the ambi ent 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 method of calculating the power consumption Pc (W) is as follows.
Pc = (Vcc-Vo) × Io ＋ Vcc × Icca
Acceptable loss Pd≦Pc
Solving this for load current IO in order to operate within the acceptable loss:
Io≦
(Please refer to Fig.10 and 22 for Icca.)
It is the n possibl e to find the maxi mu m load cu r rent IoMAX with re spec t to the appl ied voltage Vcc at the time of therma l desig n.
・Calculation Example
Example 1) When Ta=85℃, Vcc=8.3V, Vo=3.3V, BA33DD0WT
Io≦ With the IC alone : θja=62.5℃/W → -16mW/℃
Io≦200mA (Icca : 2mA) 25℃=2000mW → 85℃=1040mW
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 c urrent
●Peripheral Circuit Considerat ions
・Vcc Terminal
Please attach a capacitor (greater than 0.33µF) between the Vcc and GND.
The capaci tance values w ill dif fer depending on the applica tion, so please t ake this into a ccount w hen 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. T herefore, pl eas e reduce the im ped ance by making the gro und patterns as wide
as possible and by reducing the distance between the set ground and the IC ground as m uch as possible.
・CTL Terminal
The CTL terminal is tu rned ON at 2 .0V and higher and OFF a t 0.8V and low er w ithin the opera ting power supply voltage range.
CC0xx series, the power supply and the CTL terminal in any order without problems.
●Vo Terminal

(BAxxCC0) (BAxxDD0)
Please attach an anti-oscillation capacitor between V o 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 Fig.32 through 34. In applic ations
where there are sudden load fluctuations, the use of a capacitor with large capacitance is recommended.

●Operational Notes
1) Protection Circuits
Over-current Protection Circuit
A built-in ov er-current protection c ircuit correspondi ng to the current capacity prev ents the destr uction of the I C when there
are load shorts. This protection circuit is a “7”-shap ed cu rren t 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 Fig.6 and 18).
Thermal Shutdown Circuit (Thermal Protection)
This system has a built-in temperature protec tion circuit for the pur pose 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
Fig.14 and 26 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 revers e 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).
Fig.35 Bypass diode
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 this P-layer and the N-laye r of each device, and the P-N junction operates as a parasitic
diode when the electric potential relationsh ip is GND> Pin A, GND> Pin B, while it operates as a parasitic transistor when
the electric potential relationship is Pin B GND> Pin 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, applyi ng a voltage that is lower than the GND (P-board) to the input terminal.
