R5972D Datasheet Up To 1.5a Step-down Switching Regulator

Manufacturer: STMicroelectronics

Overview: R5972D Up to 1.5 A step-down switching regulator for aerospace applications Datasheet - preliminary data – Advanced mold and frame designs for superior resilience in harsh environments (acceleration, EMI, thermal,.

General Description

The R5972D is a step-down monolithic power switching regulator with a minimum switch current limit of 1.8 A so it is able to deliver up to 1.5 A DC current to the load depending on the application conditions.

The output voltage can be set from 1.235 V to VIN.

The device uses an internal P-channel DMOS transistor (with a typical RDS(on) of 250 m) as a switching element to minimize the size of the external components.
