PMIC - Voltage Regulators - Linear

TC1174VUATR is a low-voltage high-performance three-terminal linear regulator specifically designed for low-voltage applications, such as mobile and Tablet markets. It provides stable 3.3V output with up to 500mA output current.

Application Field of TC1174VUATR

The features of TC1174VUATR make it a perfect fit for mobile and tablet, particularly in the aspect of performance, size and cost. Firstly, it supports a wide input voltage range from 3V to 28V, making it suitable for various products. Secondly, its quiescent current of only <20μA is ideal for power-sensitive applications. Last but not least, internal current limiting and thermal shutdown protection makes the device very reliable and durable.

Working Principle of TC1174VUATR

The operation mode of TC1174VUATR is very similar to that of an Adjustable Voltage Regulator. Unlike devices such as the MPC1154, it does not contain an internal voltage reference or any adjustable features. Instead, the output voltage is set by an external voltage divider.The way it works is quite simple. The input voltage passes through the internal voltage regulator and is then output as a regulated voltage. The output voltage level can be adjusted by changing the values of the external resistors. This means that the device can be used to regulate any voltage from 0.8V to 28V.On the other hand, the device also offers several protections and features to make it reliable in various applications. It includes short circuit protection, fold-back current limiting, under-voltage lockout, and an output voltage adjust pin to enable power-down mode.

Conclusion

The combination of its impressive features make the TC1174VUATR a great fit for any low voltage application. Its wide input voltage range, low quiescent current, and low dropout voltage are ideal for power-sensitive applications. Additionally, its protection features make it a reliable and efficient linear regulator.
