DESCRIPTION  
TheSP4446 isamicropowerBoostRegualtorina5-leadSOT-23package. Itisacurrentlimited,  
fixed off time regulator configured for use in boost mode applications. The operating voltage can  
be less than 3V and is capable of generating voltages as high as 30 Volts.  
The SP4446 is to be supplied in a SOT-23-5 and permits the construction of complete regulators  
that occupy < 0.2 square inches of board space.
