PMIC – Voltage Regulators - Linear, especially the LT3081ET7#06PBF, is an integrated circuit used to provide the required voltage in the power systems. The power system may include linear regulators, switching power supplies and DC-DC converters. The main application fields of LT3081ET7#06PBF are in power systems, where the low noise and high accuracy of the supply voltage is needed.

The LT3081 series are high-speed, high efficiency, low-noise voltage regulators engineered for demanding applications. They are designed to provide tight line and load regulation, low noise and low output voltage ripple. The operating frequency of the regulator is typically around 100 kHz, allowing the user to reduce the size of key components, such as the input and output capacitors, while maintaining desired performance. The LT3081 series is available in a wide range of output voltages (4.5V to 28V) and package types for a variety of applications.

Working Principle

The LT3081ET7#06PBF works on the same basic principle as other linear voltage regulators. It takes input voltage and through various components, such as a control transistor, output capacitor, and a feedback network, produces a regulated output voltage.

The input voltage is applied to the base of the control transistor (also known as the series pass element), whose emitter is connected to ground. At the same time, the output capacitor is connected between the collector of the control transistor and the regulated output voltage. Since the control transistor is connected in series with the output capacitor, it allows the current to flow through the circuit.

The output voltage is set by a feedback network. The feedback network consists of a network of resistors and capacitors. The resistance value of these components is set so that the output voltage will be at the desired level.

The LT3081ET7#06PBF also contains an integrated error amplifier. The error amplifier is used to sense any difference between the output voltage and the set potential. When the output voltage deviates from the set level, the error amplifier produces a control current that is used to adjust the voltage across the control transistor.

This voltage is then used to control the collector-emitter voltage across the control transistor, thus changing the emitter current and resulting in the regulation of the output voltage. The output voltage will remain constant and will be set at the desired level until the input voltage changes or the load current changes.

In summary, the LT3081ET7#06PBF is a linear voltage regulator that is designed to provide tight line and load regulation, low noise, and low output voltage ripple. Its main application field is in power systems and its main features are wide range of output voltages, high speed, high efficiency, and low-noise performance. Its main components are the control transistor, output capacitor, feedback network, and integrated error amplifier. The control transistor is connected in series with the output capacitor, so that when the input voltage is applied to the base of the control transistor, the control transistor allows the current to flow through the circuit. The output voltage is set by the feedback network, and the error amplifier is used to sense any difference between the output voltage and the set potential. Finally, the output voltage will remain constant and will be set at the desired level until the input voltage changes or the load current changes.
