the use of small, low cost inductors. Only three  
external components are needed: an inductor a  
diode and an output capacitor.  
The ST5R00 is suitable to be used in a battery  
powered equipment where low noise, low ripple  
and ultra low supply current are required. The  
ST5R00 is available in very small packages:  
SOT23-5L.  
Typical applications are pagers, cameras & video  
camera, cellular telephones, wireless telephones,  
palmtop computer, battery backup supplies,  
battery powered equipment.  
DESCRIPTION  
The ST5R00 is an high efficiency VFM Step-up  
DC/DC converter for small, low input voltage or  
battery powered systems with ultra low quiescent  
supply current. The ST5Rxx accept a positive  
input voltage from start-up voltage to V  
convert it to a higher output voltage in the 2.5 to  
and  
OUT  
5V range.  
The ST5R00 combine ultra low quiescent supply  
current and high efficiency to give maximum  
battery life. The high switching frequency and the  
internally limited peak inductor current, permits
