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. An internal oscillator fixes the switching frequency at 250 kHz. The large ambient temperature range makes it ideal for aerospace and defense applications. A pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short-circuit protection. SO-8
