Introduction to TC1173–2.8VUATR

TC1173-2.8VUATR is a linear voltage regulator developed by microchip, which has the ability to provide power and small heat generation. It has a low input voltage range, high output current, high noise suppression, and high gate-source threshold voltage. It is mainly used to stabilize voltage, mainly used in high current applications and in devices such as automotive, electrical, and telecommunications systems.

Application Field

TC1173-2.8VUATR can be used for various applications where a reliable amount of regulated power is required, such as supplying a power source for different types of home and commercial appliances. It can be used in a variety of automotive applications, such as stabilizing the voltage in the battery and protecting the electrical components from power surges. It is also suitable for stabilizing the output voltage in uninterruptible power supplies, power inverters, power supplies, solar power systems, and communication systems.

Working Principle

TC1173-2.8VUATR works using feedback control. The device consists of an operative amplifier and a current-referencing network. When the external circuit is closed, the differential input voltage of the op-amp is compared with an internal reference voltage. The error signal is then fed back to the output voltage. The voltage is adjusted accordingly and regulated to a specific level. The voltage regulator also features an input voltage limit protection. If the input voltage is higher than the specified maximum voltage, the regulator detects the abnormality and limits the output voltage in order to protect the device from damage. It also has an over-temperature protection feature that monitors the temperature of the device and cuts off output to the load if the temperature exceeds the specified threshold.

Conclusion

In conclusion, TC1173-2.8VUATR is a linear voltage regulator developed by microchip and is mainly used for high current applications in automotive, electrical and telecommunications systems. It works using feedback control: the device consists of an operational amplifier and a current-referencing network. It also has input voltage limit protection and an over-temperature protection feature.
