I am looking for an LDO capable to generate output voltages from 0-8 volt at 5 Amps output current.
Output voltage level will be controlled by a DAC
It is necessary that this LDO provides reverse current blocking.
Looking forward to your answers,Niels
I can only find LT1084 that can support up to 5A. The LT3083 you asked in separate thread can only support up to 3A. The pass device is a BJT similar to LT3083 so I assume reverse leakage current…
I forgot to mention that we have LDO's that have Quick Output Discharge function that's designed to avoid reverse current in the event that VIN goes off faster than VOUT when there's big capacitance at output. I'm not sure if LT1084 has this feature though.
you are right. The LT3083 has only 3A, but I planned to compensate this by using two parts in parallel, current sharing, configuration.
A quick output discharge function is not what I was looking for. I am looking for the ability to block external applied voltages.
Anyway, many thanks for your help.
