Working principle

The TA4808BF is a linear voltage regulator, meaning that it converts a unregulated input voltage, to a regulated output voltage. This is accomplished with the use of an integrated voltage reference and multiple error amplifiers. When the output voltage of the circuit deviates from the reference voltage , the error amplifiers generate correction signals that are sent to an internal control loop, adjusting the output voltage to the desired level. The voltage reference is also used to compensate for temperature and current fluctuations.

Applications

The TA4808BF is suitable for use in a range of applications, from audio and home theatre equipment, to automotive and industrial systems. It can be used to provide regulated output voltages in 12v battery systems and automotive electronics, controlled lighting, digital surveillance systems, and power regulation. It can also be used in automotive electronic circuits, such as electronic control modules and ignition systems.

Conclusion

The TA4808BF is a breakthrough integrated circuit for low supply voltage linear voltage regulation applications. It provides adjustable output voltages up to 15V, an efficiency of up to 98%, and a quiescent current of only 13uA. It is suitable for a range of applications, from consumer electronics to automotive and industrial systems.
