LT3023EDD Application Field and Working Principle

LT3023EDD is a high performance, low-power, dual-channel low-dropout linear regulator from the Linear Tech family. It is designed to provide up to 800 mA of adjustable current, and each channel is capable of sinking current as low as 1 uA. It is also well-suited for a variety of application fields, including automotive, mobile, industrial, and medical. It operates from a wide 4.5V to 16V input range, and it is capable of providing up to 4 times more current than typical discrete LDOs in many cases.

The LT3023EDD features an integrated shutdown switch and a precision enable pin that can be used to put the regulator in low-current standby mode. It also has an adjustable under-voltage lockout that protects the output voltage as the input voltage approaches the minimum input voltage. It is also capable of both in-circuit and out-of-circuit programming, which allows it to be used in a variety of applications.

The LT3023EDD has an improved load transient performance over conventional regulators, making it suitable for high current applications that require transient response to load step changes. It also offers improved EMI performance and has a maximum output noise of 10mVpp. It has a good thermal performance, and its optimum power dissipation is 91mW.

The working principle of LT3023EDD is based on the classic Voltage-in, Voltage-out principle that is common to most linear regulators. In this topology, the regulator is designed to maintain a constant output voltage at the output, regardless of changes in the input voltage or load current. This is accomplished by comparing the output voltage to an internal reference voltage, and then using an error amplifier to adjust the output voltage of the regulator to match the reference voltage.

The LT3023EDD is an improved version of the classic linear regulator, offering better transient performance, improved EMI performance and low operating power. It is well suited for power-sensitive applications such as automotive, industrial and medical applications. The regulator is easy to use and can be programmed in-circuit or out-of-circuit. Its low operating power, wide input and output ranges, and improved load transient performance make it a great choice for almost any application.
