LP873220RHDR Product Details
LP873220RHDR Description
LP873220RHDR is a type of dual linear regulator specifically designed to meet the power management requirements of the latest processors and platforms in industrial applications. High efficiency over a wide output-current range can be obtained during the automatic PWM/PFM (AUTO mode) operation. IR drop between the regulator output and the point-of-load (POL) can be compensated based on remote voltage sensing. It is able to support load-current measurement requiring no external current-sense resistors.
LP873220RHDR Features
Device operating temperature range: –40°C to +125°C ambient temperature
