Description

The LT8636JV#WTRPBF is a low-noise, high-performance, step-down (buck) switching regulator produced by Analog Devices (formerly Linear Technology). It features a wide input voltage range, typically from 3V to 15V, and can efficiently deliver up to 2A of output current. The device is designed for applications requiring low output ripple and noise, making it suitable for powering sensitive analog and RF circuits.
Key features include a high switching frequency, which allows for smaller external components, and an adjustable output voltage down to 0.8V. It also incorporates various protection mechanisms such as thermal shutdown and overcurrent protection. The LT8636 operates in a burst mode to improve efficiency at light loads, further enhancing its applicability in battery-powered devices.
The package type (JV) is a thermally enhanced 4mm x 4mm QFN, allowing for efficient heat dissipation. Overall, the LT8636JV#WTRPBF is ideal for applications like portable equipment, industrial automation, and RF systems where low noise and compact design are critical.

Features
