DESCRIPTION  
The ST750A is an adjustable output CMOS,  
step-down switching regulator. The ST750A  
accepts inputs between 4V and 11V and delivers  
450mA. Typical efficiencies are 85% to 96%.  
Quiescent supply current is 0.8mA and only 0.3µA  
in shutdown mode. The output does not exhibit  
frequency over this specified range. Pulse-width  
modulation (PWM) current-mode control provides  
a
single inductor value to work in most  
applications, so no inductor design is necessary.  
Typical applications are: Cellular phones & radios,  
portable Instruments, Portable Communications  
Equipments and Computer Peripherals.
