Introduction

The LT1964EDD#TRPBF is a low-dropout linear voltage regulator, which is used in a variety of applications, such as high-performance, low-noise, high-reliability operation. It is designed to provide consistent, reliable output voltage regulation and improved power supply design. The LT1964EDD#TRPBF, in particular, was specifically designed to provide low-noise, high-efficiency voltage regulation, with minimal power dissipations.

Application Fields

The LT1964EDD#TRPBF is a low-dropout linear voltage regulator that is ideal for applications requiring high-performance, low-noise, high-reliability operation. It is designed for use in applications such as industrial machines, automotive, telecom, consumer electronics, portable products, and many other space-constrained applications.

With its low quiescent current, the LT1964EDD#TRPBF is extremely suitable for power supplies with minimum power drawbacks such as those used in audio amplifiers and portable and automotive electronics. Moreover, with its tight output voltage regulation and wide operating temperature range, it is particularly useful for portable and automotive devices, as well as in high-reliability operation.

The LT1964EDD#TRPBF is also suitable for low-power systems, as it features an output shutdown feature for applications requiring power savings. Moreover, it features also an internal reference voltage of 2.5V and an adjustable output voltage, allowing users to adjust the desired output voltage range to their specific needs.

Working Principle

The working principle of the LT1964EDD#TRPBF is relatively simple. It uses a simple feedback circuit where the voltage regulator senses the output voltage and then compares it to a reference voltage. If the output voltage is lower than the reference voltage, it will increase the output voltage, and if the output voltage is higher than the reference voltage, it will decrease the output voltage.

At the heart of the regulator is a pass element, which is typically an N-MOSFET or P-MOSFET, depending on the type of regulator. The pass elemenｔ is connected in series with the output load, and its gate voltage is controlled using a feedback circuit. The feedback circuit monitors the output voltage, and adjusts the gate voltage of the pass element to increase or decrease the output current, based on the difference between the output voltage and the reference voltage. In this way, the output voltage can be kept constant, regardless of changes in the input voltage or output load current.

In addition to the low-dropout linear voltage regulator features, the LT1964EDD#TRPBF also comes with several protection features. It has internal thermal protection, which uses an NTC thermistor to protect the regulator from over temperature conditions. It also has short circuit protection, which limits the current of a short circuit loop from going above a certain level, and over voltage protection, which monitors the output voltage and shuts down the output at a predetermined level.
