Introduction: The LT3065HMSE-3.3#PBF is a low dropout voltage (LDO) linear regulator with a wide input voltage range and low quiescent current operating from a single 3.3V output. It is a monolithic, positive, low dropout linear regulator with internal power MOSFET, ideal for applications where high current is required. The LT3065HMSE-3.3#PBF provides a regulated 3.3V output with an adjustable current limit of up to 2A. With excellent load and line regulation characteristics, it is an ideal choice for precision power supplies and ultra-low-noise, low-power systems.

Application field: The LT3065HMSE-3.3#PBF is widely-used in a variety of applications, such as Telecommunications, medical, industrial, consumer and automotive. In Telecommunications, it is used in Sonet, DSL, T1/E1, Ethernet and other data communications equipment. It is also ideal for use in medical and industrial equipment, where high reliability and low noise are essential. In consumer applications, the LT3065HMSE-3.3#PBF can be used in media players, set-top boxes, portable DVD players, digital picture frames and USB battery chargers. Finally, in automotive applications, the LT3065HMSE-3.3#PBF can be used in CAN bus environments, as an adjustable current source for gates, controllers and other automotive microcontrollers, as well as a direct 3.3V supply for active components.

Working Principle: The LT3065HMSE-3.3#PBF operates like all conventional linear regulators, using a power MOSFET as a pass transistor to regulate the output voltage. The input voltage is applied to the gate of the MOSFET and the output voltage is connected to the source. The difference between the input and output voltage is known as the voltage dropout, which is the voltage that must be present at the input in order for the regulator to maintain the output. The LT3065HMSE-3.3#PBF is a low dropout device and supports a wide input voltage range of up to 36V, making it ideal for applications where input voltage may vary. The device has an adjustable current limit, allowing the user to set the maximum current through the output. This feature prevents the device from exceeding a certain current level and damaging other components.

The LT3065HMSE-3.3#PBF also has a number of other features that make it an excellent choice for precision power supplies and ultra-low noise, low-power systems. It incorporates an ultra-low quiescent current, which minimizes power dissipation and reduces system power costs. Additionally, it has an internal voltage reference, making it ideal for use in isolation transformer applications. The device also features reverse-battery protection which prevents damage to the system in the event of a reverse battery connection. Finally, the LT3065HMSE-3.3#PBF operates over an extended temperature range of -40°C to +125°C and is available in a small 8-pin Thermally Enhanced TSOT (2mm x 3mm) package.

Conclusion: The LT3065HMSE-3.3#PBF is a high-performance, low dropout linear regulator with an adjustable current limit of up to 2A. It has a wide input voltage range of up to 36V and an extremely low quiescent current. It is an ideal choice for use in precision power supplies, telecommunications, medical, industrial, consumer and automotive applications. With its high power efficiency, excellent line and load regulation, reverse-battery protection, extended temperature range and small package size, the LT3065HMSE-3.3#PBF makes an excellent choice for ultra-low-noise, low-power systems.
