The LTC3129-1 employs an ultralow noise, 1.2MHz PWM  
switchingarchitecturethatminimizessolutionfootprintby  
allowing the use of tiny, low profile inductors and ceramic  
capacitors. Built-in loop compensation and soft-start  
simplify the design. For high efficiency operation at light  
loads, automatic Burst Mode operation can be selected,  
reducing the quiescent current to just 1.3µA. To further  
reduce part count and improve light load efficiency, the  
LTC3129-1 includes an internal voltage divider to provide  
eight selectable fixed output voltages.
