Hi, I am designing a general purpose LDO with external input reference. I have the samples of NE57814. Can someone help me regarding the following questions?
(1) From the datahsheet it says max VD and VDD=3.6V. If I am using VD=VDD=5.5V, will it break the circuit or make it unfunctional? I am not doing mass production. So as far as it still functions, that is good for me.
(2) Can I connect external resistor dividers to close the feedback loop (I do not want VTT=VREF, but VTT=K*VREF, where K is a number greater than 1)? If so, how can I connect it? The question is illustrated in the attachment.
(3) If I cannot use NE57814, are there any other products I can choose, which can be used as the LDO with external input reference signal?
