LT3971EMSE#PBF Description

Short technical summary and product information.

The LT3971EMSE#PBF is a monolithic buck regulator manufactured by Analog Devices. It features a wide input voltage range from 4.3V to 38V and can deliver up to 1.2A of output current. The device operates with an adjustable switching frequency from 200kHz to 2MHz, allowing for optimization of efficiency and component size.

 

A key feature is its ultralow quiescent current of 2.8µA, which is beneficial for battery-powered applications. It also includes features like a power good flag, soft-start capability, and internal compensation.

 

This regulator is available in a small, thermally enhanced 10-lead MSOP package, suitable for space-constrained designs. The operating temperature range is -40°C to 125°C.

 

It is classified under Power Management ICs, specifically within the Voltage Regulators - DC DC Switching Regulators category.
