It is also known as a linear voltage regulator, which is an electronic device for maintaining a given output voltage under a wide range of input voltages. The TC1264-2.5VAB belongs to a group of low-dropout voltage regulators and is a popular choice for wide applications in electronic circuits requiring a regulated supply voltage.

Application Field

The TC1264-2.5VAB is a versatile voltage regulator that is typically found in board level and remote applications. It is used in power supplies, LED lighting and other systems equipped with a wide range of input voltages, and also in audio systems, precision instrumentation and microcontroller-based applications. As a three-terminal device, it is also used in many motor driver applications, providing stability and reliable voltage.

Working Principle

The TC1264-2.5VAB is an integrated linear voltage regulator which controls the output voltage by means of a voltage reference circuit. It works by comparing the output voltage of the device to an internal reference. The output voltage is adjusted so that it surpasses the internal reference, and this is done by driving an error amplifier. The error amplifier adjusts the output voltage to the specified value, and keeps it at that value even when the input voltage changes. The output is then stabilized by employing a series of current-limiting and temperature compensation techniques.

The TC1264-2.5VAB also incorporates a protection feature to avoid damage to the device should it exceed its power dissipation. It employs a thermal shutdown feature which shuts off the device in case the junction temperature rises above the specified limit. This prevents the device from burning out due to excessive heat.

Conclusion

The TC1264-2.5VAB is a versatile and robust type of linear voltage regulator that provides a low drop-out, highly accurate, and tightly regulated output voltage. Its three-terminal design and protection features make it suitable for a wide range of applications in board level and remote systems, motor drivers, and LED lighting, among others. It can also be used in precision instrumentation and microcontroller-based applications. The device ensures a stable output voltage even when the input voltage changes, and is capable of withstanding high temperatures in case of overload.
