TC1173-2.5VOA is a two-terminal linear voltage regulator designed to supply up to 500mA current with an adjustable output voltage between 1.25V and 28V. It is ideal for providing regulated outputs from fluctuating inputs and offers low cost, high accuracy, high power supply rejection, and easy to use features. The device is a modern, low power, low noise linear voltage regulator. It is available in different packages to suit various applications.

The TC1173-2.5VOA can be used for a wide range of applications such as powering precision analog circuitry, powering digital logic and application-specific integrated circuits (ASICs) with a regulated voltage, and providing a constant voltage supply for charge pumps, switching regulators, and microprocessors. Its large input voltage range can accommodate higher voltages from incoming supplies and its high accuracy allows for the design of power supplies that require less trimming. Furthermore, the TC1173-2.5VOA also features overcurrent protection, short-circuit protection, and thermal shutdown protection.

The principle of operation of the TC1173-2.5VOA is based on a standard 3-terminal linear regulator, with both the input and output pins connected directly to ground. It is designed so that the output voltage is regulated according to a resistive voltage divider, which both allows the output voltage to be adjustable and provides feedback to the device. As the input voltage applied to the device increases or decreases, the feedback signal follows it and adjusts the amount of current flowing to the output as needed. This way, the output voltage remains constant regardless of the input voltage, making the TC1173-2.5VOA ideal for applications requiring a steady output voltage from a wide range of input supply voltages.

The TC1173-2.5VOA is a versatile voltage regulator with a wide range of applications from low-power digital logic, to high-power charge pumps, to precision analog circuitry. It offers a large input voltage range, high accuracy and precision, low-noise, low-power consumption, and numerous safety features, making it suitable for a variety of applications. It also offers short circuit protection, overcurrent protection, and thermal shutdown protection, ensuring robust, reliable operation.
