provide a complete power management solution  
for TI DSP, processor power, ASIC, FPGA, and  
digital applications where dual output voltage  
regulators are required. Easy programmability of  
the sequencing function makes this family ideal  
for any TI DSP applications with power  
sequencing requirement. Differentiated features,  
such as accuracy, fast transient response, SVS  
supervisory circuit (power on reset), manual reset  
inputs, and enable function, provide a complete  
system solution.
