Regulator ICs BAΟΟST / BAΟΟSFP series Regulator, low drop-out type with ON/OFF switch BAΟΟST / BAΟΟSFP series The BAΟΟST and BAΟΟSFP series are variable, fixed output low drop-out type voltage regulators with an ON/OFF switch.

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 22m F capacitor is recommended; however, be aware that if an extremely large capacitance is used (1000µF 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 0.33m F bypass capacitor as close as possible between the input pin and GND. (4) Current overload protection circuit A current overload protection circuit is built into the outputs, to prevent IC destruction if the load is shorted. This protection circuit limits the current in the shape of a ‘7’. It is designed with a high margin, so that even if a large current suddenly flows through the large capacitor in the IC, the current is restricted and latching is prevented. However, these protection circuits are only good for pre-venting damage from sudden accidents. The design should take this into consideration, so that the protection circuit is not made to operate continuously (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 various outputs are in the OFF state. 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 of the various 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 measure. (8) When used within a strong magnetic field, be aware that there is a slight possibility of malfunction. Regulator ICs BAΟΟST / BAΟΟSFP series (9) When the connected load which contains a big inductance component in an output terminal is connected and the occurrence of a reverse electromotive force can be considered at the time of and power-output OFF at the time of starting, I ask the insertion of protection diode of you. (Example) Output pin (10) Although it is sure that the example of an application circuit should be recommended, in a usage, I fully ask the validation of a property of you. In addition, when you alter the circuit constant with outside and you become a usage, please see and decide sufficient margin in consideration of the dispersion in an external component and IC of our company etc. not only including the static characteristic but including a transient characteristic. This IC is monolithic IC and has P+ isolation and P substrate for an isolation between each element. A P-N junction is formed by these P layers and N layers of each element, and various kinds of parasitic elements are formed. For example, when the resistor and the transistor are connected with the pin like the example of a simple architecture, •At a resistor, it is at the time of GND > (PIN A), at a transistor (NPN), it is at the time of GND > (PIN B), A P-N junction operates as parasitism diode. •At a transistor (NPN), it is at the time of GND > (PIN B), The NPN transistor of a parasitic element operates by N layers of other elements which approach with the abovementioned parasitism diode. A parasitic element is inevitably made according to a potential relation on the architecture of IC. When a parasitic element operates, the interference of a circuit operation is caused and the cause of a malfunction, as a result a destructive is obtained. Therefore, please be fully careful of impressing a voltage lower than GND(P substrate) to an input/output terminal etc. not to carry out usage with which a parasitic element operates.
