Linear voltage regulators are usually the first choice for applications that require a precise, regulated output voltage from a DC/DC converter or a power supply. The LT3080EST#TRPBF from Linear Technology is a low dropout (LDO) linear regulator specifically designed to provide precise, low noise and low quiescent power operation over a wide range of input and output voltages. It is a high-performance linear voltage regulator with excellent transient response, low noise, low dropout and high power efficiency.

The LT3080EST#TRPBF is a monolithic integrated circuit that uses a low voltage CMOS process to achieve low supply current and low output voltage. The device consists of an internal voltage reference, an error amplifier, a power MOSFET pass transistor, compensation components and a power supply decoupling network. It is designed to provide a regulated output voltage from 4.2V to 24V, with a maximum output current of 1.3A. The device also has shutdown and soft start features for better performance and protection against over-voltage, current limit and thermal protection.

The LT3080EST#TRPBF offers superior performance and reliability, making it an ideal choice for applications that require low noise, low power and high efficiency operation. It is well suited for powering digital logic devices and other sensitive analog components required by systems such as sensor nodes and RF transceivers. It is also well suited for automotive, industrial and medical applications, where high efficiency and low quiescent supply current are essential.

The basic working principle of the LT3080EST#TRPBF is simple. The output voltage of the device is regulated by comparing the feedback voltage from the actual output with the reference voltage. The error amplifier senses the difference between the actual output voltage and the reference voltage and amplifies it, and then drives the MOSFET to adjust the output voltage to the desired value. The reference voltage is generated by the internal reference of the device, which is designed to be stable, precise, and low noise. The internal voltage reference is supply current independent, allowing the LT3080EST#TRPBF to achieve high accuracy and low noise without the need for additional external components.

The LT3080EST#TRPBF is a high performance linear voltage regulator which offers both excellent transient response and low noise performance. It features a low dropout voltage, high power efficiency and low quiescent current. In addition, it has integrated protection features including over-voltage, current limit, thermal protection and soft start. The device is suitable for powering digital logic devices and other sensitive analog components in a wide range of applications requiring low noise and low power consumption.
