Introduction:
The LT3065EDD-3.3#TRPBF is a high-efficiency, low quiescent current (QC), linear regulator with a 3.3V regulated output voltage, accurate line- and load-transient tracking, and excellent load and line regulation. It is available in a 6-pin SOT-23 package. It is ideal for use in low-power applications, especially for portable or battery-powered equipment such as cell phones, PDAs, and notebook computers as well as in other applications that require low power consumption and small size.

Application Field:
The LT3065EDD-3.3#TRPBF has a wide range of applications, including voltage regulation in automotive, communication, industrial and medical designs. It can be used as a replacement in many existing circuits as a low-power, highly efficient voltage regulator. This device offers excellent load- and line-transient tracking and high power efficiency, which makes it suitable for use in low-power applications such as PDAs, cell phones, and notebook computers. It can be used in power management systems, power amplifiers, and portable instrumentation. It can regulate current in a variety of computer-related applications, including powering a hard disk drive and regulation in power-over- Ethernet systems. The LT3065EDD-3.3#TRPBF also provides output adjustable voltage, and can be configured as voltage references or voltage followers.

Working Principle:
The LT3065EDD-3.3#TRPBF incorporates a fixed-frequency, current-mode, switching regulator which is controlled by a voltage-mode cycle-by-cycle current limit, current-sense amplifier and a precision reference. The switched regulator generates a voltage to be applied to the output, and the feedback loop reacts swiftly to any changes in the output voltage, thereby providing good line and load regulation. The precise output voltage is determined by the internal reference voltage. The current being supplied by the input voltage is accurately regulated by controlling the duty cycle of the switching regulator. The LT3065EDD-3.3#TRPBF is able to maintain a very low output voltage ripple and noise, and has a fast transient response. It is also able to maintain a good output voltage accuracy even with varying load and line conditions. The LT3065EDD-3.3#TRPBF has a built-in thermal limiting protection circuitry to protect itself from damage due to overheating. It also offers an adjustable current-limit feature to provide further protection against component damage due to overloading or fault conditions.

Conclusion:
The LT3065EDD-3.3#TRPBF offers an efficient, low-power linear voltage regulation solution with a 3.3 V regulated output voltage, accurate line- and load-transient tracking, and excellent load and line regulation. It is well suited for use in low-power applications such as cell phones, PDAs, and notebook computers. It is also ideal for use in voltage regulation in automotive, communication, industrial and medical designs. The LT3065EDD-3.3#TRPBF also offers protection against overheating and overloads, thanks to its thermal limiting circuitry and adjustable current-limit feature.
