Introduction

The TS14002-C028DFNR is a three-terminal well-regulated linear voltage regulator which is capable of supplying a fixed output voltage with a load current up to 2.25 amps. The voltage regulator can operate between an input voltage range of 10V to 18V. The device has an adjustable current limit, thermal shutdown and features an asynchronous current limit and a preconditioning delay to prevent an initial inrush current.

Properties and Features

The TS14002-C028DFNR is designed to operate with a high power density making it ideal for applications such as portable devices, DC-DC converters, voltage regulators, and high power monitors. It is also capable of operating at high frequencies and is equipped with an adjustable current limit, thermal shutdown and an over-voltage protection function.The output voltage can be set by two external resistors. The device also has a thermal shutdown protection which will be activated when the junction temperature rises above 165C and the output voltage will drop to 1.25V. The output voltage is also protected against excessive current, over voltage and reverse voltage.

Applications

The TS14002-C028DFNR is widely used in many applications such as portable and stationary instrumentation, motor controls, signalling and communication equipment and automotive electronics. In addition, the device is also suitable for use in high power and high frequency applications such as DC-DC converters, switching regulators and motor speed control.

Working Principle

The TS14002-C028DFNR voltage regulator works by comparing the output voltage with a reference voltage that is set by two external resistors. The error signal is used to control the magnitude of the voltage and current at the output.The device is designed to provide high power output in a very small package. It is capable of operating at high frequencies and is equipped with an adjustable current limit, thermal shutdown, and over-voltage protection function.The output voltage is maintained by a voltage reference circuit with an internal voltage reference device that is adjusted by two external resistors to supply an accurate voltage output.The device works in a continuous conduction mode and the current capable of being delivered is limited by a maximum output current of 2.25A. The device features an asynchronous current limit, meaning that it can shut down its own output if the current limit is exceeded. This ensures that your power supply will be protected against any short circuit or overload conditions.Furthermore, the device has a preconditioning delay which is activated when an inrush current is detected. This prevents any initial damage that could occur due to the high inrush current. Additionally, the device has a thermal shutdown protection which will be activated when the junction temperature rises above 165C and the output voltage will drop to 1.25V.

Conclusion

The TS14002-C028DFNR is a three-terminal well-regulated linear voltage regulator which is capable of supplying a fixed output voltage with a load current up to 2.25 amps. It is designed to operate with a high power density, making it ideal for applications such as portable devices, DC-DC converters, voltage regulators, and high power monitors. The device has an adjustable current limit, thermal shutdown and features an asynchronous current limit and a preconditioning delay to prevent an initial inrush current. The voltage output is determined by two external resistors allowing for flexible and accurate regulation. Finally, the device is protected against over current, over voltage and reverse voltage.
