R5973AD Overview
The R5973AD 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 high current level is also achieved thanks to an HSOP8 package with an exposed frame, that allows to reduce the Rth(JA) down to approximately 40 °C/W.
