Hi friends:
Now i am designing LDO buffer stage.I used a rail-to-rail amplifier with unity-gain feedback configuration. Then i have some problems:
1.Because the rail-to-rail amplifier i used is unity-gain feedback configuration,so it must be stable,so how to compensate it to be stable?
2.Because the cap load of the buffer is as big as 80pF, how to enhance the output slew-rate capability of the buffer?
Please help me! thanks a lot!
