Overview
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 is also thanks to a HS package with exposed frame that allows to reduce the Rth( JA) down to approximately 40 °C/W. The output voltage can be adjusted from 1.22 V. The device uses an internal N-channel DMOS transistor (with a typical RDS(on) 200 mΩ) as the switching element to minimize size of the external components. The internal oscillator fixes the switching frequency at 850 kHz. Power good open collector output validates the regulated output voltage as soon as it enters the regulation. Pulse-by-pulse current limit offers an effective constant current short-circuit protection.
