I need a shutdown crcuit for my LDO. Who can show me the paper or schematic?
Thanks.
 

There is no specific circuit that will accomplish shutdown.

What you need to do is "AND" your enable/shutdown pin with your start up circuit; and, pull down/up the high impedance nodes to vdd and gnd. If you have simplified ckt, do post it. I am assuming this is a CMOS process
