• Ability to regulate voltage to within 1% of the target output voltage over the entire input voltage range
• Suitable for use in consumer electronics, automotive and communications applications

Working Principle

The TC1263-2.8VOATR is a linear voltage regulator, which means that it uses a series of components to regulate the input voltage and provide a stable output voltage. This is done by using three components: a reference voltage source, an error amplifier, and a pass element.

The reference voltage source is a precision voltage source, which provides a fixed output voltage which does not vary with temperature or other environmental conditions. The error amplifier is a differential amplifier, which compares the output voltage to the reference voltage and produces an output signal proportional to the difference between the two values. Finally, the pass element is an active device (such as a transistor, MOSFET or an IC) which is used to control the amount of current flowing through the load, in order to regulate the output voltage.

When the reference voltage exceeds the output voltage, the pass element is turned on, and the current through the load is increased. This results in an increase in the output voltage, and the process is repeated until the output voltage matches the reference voltage. Similarly, when the output voltage exceeds the reference voltage, the pass element is turned off, and the current through the load is decreased, resulting in a decrease in the output voltage.

The precise operation of the voltage regulator is controlled by the error amplifier, which monitors the difference between the output voltage and the reference voltage and adjusts the amount of current flowing through the load accordingly. This ensures that the output voltage is always kept within a range of plus or minus 1% of the target output voltage, regardless of the input voltage.

Conclusion

The TC1263-2.8VOATR is an ideal choice for designs that demand wide input voltage ranges, low power, and small size. Its wide range of input voltages, low dropout voltage, and low ripple current make it suitable for a variety of applications, including consumer electronics, automotive, and communications. Its high efficiency and low heat performance make it a good choice for applications which demand reliable and stable voltage regulation.
