Low saturation voltage type 3-pin
regulator
BAOOT / BAOOFP series
The BAΟΟT and BAΟΟFP series are fixed positive output low drop-out type, 3-pin voltage regulators with positive output.
These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.
There are 10 fixed output voltages, as follows:3V, 3.3V, 5V, 6V*, 7V, 8V, 9V, 10V, 12V and 15V. The maximum current
capacity is 1A for each of the above voltages. (Items marked with an asterisk are under development.)
!Application
Constant voltage power supply
!Features
1) Built-in overvoltage protection circuit, overcurrent
protection circuit and thermal shutdown circuit.
2) TO220FP and TO252-3 packages are available to
cover a wide range of applications.
3) Compatible with the BA178ΟΟ series.
4) Richly diverse lineup.
5) Low minimum I / O voltage differential.

!Operation notes
(1) Operating power supply voltage
When operating within the normal voltage range and within the ambient operating temperature range, most circuit
functions are guaranteed.
The rated values cannot be guaranteed for the electrical characteristics, but there are no sudden changes of the
characteristics within these ranges.
(2) Power dissipation
Heat attenuation characteristics are noted on a separate page and can be used as a guide in judging power
dissipation.
If these ICs are used in such a way that the allowable power dissipation level is exceeded, an increase in the chip
temperature could cause a reduction in the current capability or could otherwise adversely affect the performance of
the IC. Make sure a sufficient margin is allowed so that the allowable power dissipation value is not exceeded.
(3) Output oscillation prevention and bypass capacitor
Be sure to connect a capacitor between the output pin and GND to prevent oscillation. Since fluctuations in the valve
of the capacitor due to temperature changes may cause oscillations, a tantalum electrolytic capacitor with a small
internal series resistance (ESR) is recommended.
A 22µF capacitor is recommended; however, be aware that if an extremely large capacitance is used (1000µ F or
greater), then oscillations may occur at low frequencies. Therefore, be sure to perform the appropriate verifications
before selecting the capacitor.
Also, we recommend connecting a 0.33µF bypass capacitor as close as possible between the input pin and GND.
(4) Overcurrent protection circuit
An overcurrent protection circuit is built into the outputs, to prevent destruction of the IC in the even the load is shorted.
This protection circuit limits the current in the shape of a ’7’. This circuit is designed with a high margin, so that that
current is restricted and latching is prevented, even if a high-capacitance capacitator causes a large amount of current
to temporary flow through the IC.
However, these protection circuits are only good for pre-venting damage from sudden accidents and should not be
used for continuous protection (for instance, clamping at an output of 1VF or greater; below 1VF , the short mode circuit
operates). Note that the capacitor has negative temperature characteristics, and the design should take this into
consideration.
(5) Thermal overload circuit
A built-in thermal overload circuit prevents damage from overheating. When the thermal circuit is activated, the
outputs are turned OFF. When the temperature drops back to a constant level, the circuit is restored.
(6) Internal circuits could be damaged if there are modes in which the electric potential of the application’s input (VCC ) and
GND are the opposite of the electric potential normally used by each of the outputs. Use of a diode or other such
bypass path is recommended.
(7) Although the manufacture of this product includes rigorous quality assurance procedures, the product may be
damaged if absolute maximum ratings for voltage or operating temperature are exceeded. If damage has occurred,
special modes (such as short circuit mode or open circuit mode) cannot be specified. If it is possible that such special
modes may be needed, please consider using a fuse or some other mechanical safety mea-sure.
(8) When used within a strong magnetic field, be aware that the possibility of malfunction exists.
