Introduction

LT1963AIFE#PBF is a low-dropout (LDO) linear voltage regulator with low noise, high ripple rejection, low dropout, and low noise, designed for easy to use in various applications. This will provide excellent performance and reliable operations with fewer external components. It works from an input voltage range of 2.3V to 30V, and it can supply current up to 950mA, while keeping the output voltage regulation within 2.5% accuracy.

Application Fields

LT1963AIFE#PBF is a reliable and very efficient, highly beneficial IC for many applications. It is often used as a low-cost alternative to conventional linear and Switch Mode Power Supply (SMPS) regulators, due to its advantages of high ripple rejection and low dropout voltage. Among its many potential applications, the LT1963AIFE#PBF can be used in industrial applications such as motor control, lighting applications, profiling systems, and audio systems, as well as in more general applications such as car audio systems, instrumentation, and personal electronics.

Working Principle

The LT1963AIFE#PBF uses a precision voltage reference and proprietary circuitry to keep a constant output voltage over a wide range of input and load conditions. The IC is designed to provide a very low dropout voltage, with an input voltage of 1.0V to 1.5V greater than the output voltage, and a very low output noise.The LT1963AIFE#PBF utilizes feedback control techniques to monitor and regulate the output voltage, by comparing the feedback voltage on the OUT pin to the internal reference. When the feedback voltage changes with the input voltage or load current, the error binding between the internal reference and the OUT pin voltage changes and triggers the dropout voltage control circuitry. The dropout control circuitry steps up or down the current through the pass transistor to keep the output voltage constant.For example, when the output load increases, the feedback voltage decreases, sending an error signal to the internal controls, which in turn increases the pass transistor current to maintain the output voltage. Similarly, should the input voltage increase, the error signal is reversed, decreasing the current of the pass transistor.In conclusion, the LT1963AIFE#PBF is a wise choice for those seeking a monolithic voltage regulator solution with enhanced features, like high ripple rejection, low dropout voltage, and very low output noise. It is an ideal solution for industrial, motor control, and other applications.
