Hello All,

I want to design 12V-5V Unregulated I/P to 3.3V,1A Regulated O/P Linear Voltage Regulator using CMOS 0.6um Technology with Cadence tool.

Can any one please suggest me correct Topology?

I have knowledge of LDO but I am not sure for this problem LDO topogoly is suitable or what because Drop out voltage range is very big.

Any reference material will also appreciated.

Thanks
