Description  
Features  
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,

approximately 40 °C/W. The output voltage can  
be set from 1.22 V. The device uses an internal N-

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 reaches  
the regulation. Pulse-by-pulse current limit offers  
an effective constant current short-circuit
