ST1S14 - STMicroelectronics

ST1S14 Up to 3A step-down switching regulator

The ST1S14 is a step-down monolithic power switching regulator able to deliver up to 3 A DC current to the load depending on the application conditions. The high current level is also achieved thanks to a HSOP8 package with exposed frame, that allows to reduce the Rth(JA) down to approximately 40 °C/W. The output voltage can be set from 1.22 V.
