Introduction

TC2185-2.85VCTTR is a linear voltage regulator designed by Taiwan Semiconductor. It is used to provide a stable output voltage for a wide range of electronic devices and applications. The device is capable of handling up to 3 amp current and can maintain a voltage up to 2.85 V. It also features over current and over voltage protection, as well as thermal shutdown protection.

Application

TC2185-2.85VCTTR is mainly used in applications which require a stable voltage source, such as communications equipment, computers, servers, and other power related projects. It is also used for voltage regulation in automotive electronic components. Additionally, it can be used for low power applications such as LED drivers.

Working Principle

The TC2185-2.85VCTTR linear voltage regulator works by controlling the output voltage of the device, by decreasing or increasing the current output. It contains two operation modes, linear and fixed voltage, which can be selected according to the requirements of the application. In the linear operation mode, the output voltage is regulated by the differential voltage across two resistive elements. This is done by allowing a current to flow through one element while blocking it in the other.In the fixed voltage operation mode, the output voltage is controlled by adjusting the current flow through the resistive elements. The current is adjusted using an external voltage source, which is also used to set the desired voltage. The fixed voltage operation mode is used when a higher voltage accuracy is required for the application.

Conclusion

The TC2185-2.85VCTTR linear voltage regulator is an ideal solution for applications requiring an accurate and stable voltage source. It is suitable for applications such as communications equipment, automotive electronic components, LED drivers, and other power related tasks. The device is also capable of providing protection from current and voltage overages, as well as thermal shutdown protection.
