Linear Technology LT3507AEUHF#PBF - Triple Output, Adjustable and Fixed Voltage Regulator

The LT3507AEUHF#PBF from Linear Technology is a robust, triple-output, adjustable and fixed voltage regulator designed to cater to a wide array of applications requiring multiple voltage rails. This versatile component is capable of driving a step-down DC/DC converter with additional two LDO regulators, making it an ideal solution for complex power supply designs.

With its wide input voltage range of 3V to 25V, the LT3507AEUHF#PBF is suitable for applications powered by a variety of sources, from single-cell Li-Ion batteries to industrial supplies. Each of the three outputs is capable of delivering significant current: the main buck converter can provide up to 1.4A, while the two LDO outputs can supply up to 400mA and 200mA respectively. This makes the LT3507AEUHF#PBF an excellent choice for powering multiple devices such as microcontrollers, sensors, and communication modules simultaneously.

The device features a high switching frequency of up to 2.2MHz, which allows the use of small, low-cost inductors and capacitors, resulting in a compact power supply solution. Additionally, the switching frequency can be synchronized to an external clock to minimize potential interference with sensitive RF or audio circuits.

The LT3507AEUHF#PBF also incorporates a range of protective features, including over-temperature protection, overvoltage and current protection, ensuring reliable operation under various conditions. The regulator's robust design also includes tracking and soft-start capabilities to provide a smooth power-up sequence for sensitive electronics.

Encapsulated in a QFN-38 package, the LT3507AEUHF#PBF is designed for efficient thermal management and minimal footprint on PCBs. Its performance and package make it an excellent choice for space-constrained applications in automotive, industrial, and portable electronics sectors.

Whether you are designing a power supply for a complex system or simply need multiple reliable voltage rails, the LT3507AEUHF#PBF from Linear Technology stands out as a high-performance, versatile solution.
