PMIC - Voltage Regulators - Linear

TC1265-1.8VOATR, a linear voltage regulator, is an integrated circuit (IC) that functions in a wide variety of applications. It is used to maintain a constant DC output voltage by compensating for variations in power supply or load. In this regard, the semiconductor device serves as the voltage regulator for an electrical system or an electronic circuit board.

The device is capable of supplying up to 1.8 V and 200 mA (depending on the package) of continuous output current. It is available in a three-pin TO-92 package, allowing it to be directly mounted on common printed-circuit boards (PCBs).

The TC1265-1.8VOATR voltage regulator is designed to operate within linear supply voltages ranging from 5 V to 24 V, making it suitable for use in all sorts of DC power systems such as personal computers, telecom infrastructure, vehicle electronics, and many more. Moreover, its excellent thermal stability, high output-current capability, wide supply voltage range, and low cost make it an attractive choice for many applications.

Application

The TC1265-1.8VOATR voltage regulator is suitable for diverse applications. While being ideal for powering low power analog, digital or mixed-signal circuits on the PCB, these devices also enable the reduction of board size by conserving space and eliminating the need for other voltage regulation components.

These devices are perfect for use in Battery-Powered Applications, such as for powering charging circuits for various portable devices, for stabilizing the output voltage in the Secondary Side of DC / DC converters, and for notebook computers, portable navigation systems, digital broadcasting equipment, and more. In addition, they provide ideal operating conditions for processor-based systems when a low operating voltage is necessary.

The device can also be employed in Linear Voltage Regulation, as it provides an extremely low-noise output voltage and regulates both load and line variations with high accuracy. This makes it well-suited for providing a highly stable voltage to support sensitive analog circuits such as amplifiers and audio signal processors.

Working Principle

The TC1265-1.8VOATR voltage regulator works by using an n-p-n transistor to operate as a variable resistor. This creates a feedback loop that ensures that the output voltage is always kept at the desired level. This is achieved by using the output voltage to adjust the transistor\'s resistance in such a way as to compensate for any fluctuations in the power supply or load. In this way, the voltage regulator is able to maintain a constant DC output.

Furthermore, this series of linear voltage regulators incorporates a low-dropout (LDO) feature, making it even more efficient at maintaining a stable voltage output. This means that the device is able to operate even under higher loads with lower supply voltages. It also has a very low output-voltage noise, making it ideal for powering sensitive components that require a noise-free voltage supply.

In conclusion, the TC1265-1.8VOATR voltage regulator is an excellent choice for providing stable and reliable DC power to a wide range of applications. It is especially suitable for use in battery-powered electronics and linear voltage regulation, as it provides a low-noise output voltage and is highly stable in operation.
