LT1767EMS8-5

The LT1767EMS8-5 is a fixed-output, step-down (buck) switching regulator designed by Analog Devices (previously Linear Technology). It is designed to efficiently convert a higher DC voltage to a stable 5V output. The device operates with input voltages ranging from 3.6V to 25V and can deliver an output current of up to 1.2A, making it suitable for a variety of applications, including battery-powered devices, distributed power systems, and point-of-load regulation.
The LT1767EMS8-5 features a high-efficiency design with a switching frequency of 1.25MHz, allowing for the use of small external components and minimal board space. It includes features like internal frequency compensation, cycle-by-cycle current limiting, thermal shutdown, and soft-start to prevent inrush current during startup. The regulator is packaged in the MSOP-8 (Mini Small Outline Package) for a compact footprint. Its design prioritizes low noise and high performance, making it an ideal choice for applications requiring stable and efficient power delivery.
