A customer asks concerning the LT3080: "We operate at: Vin = 3.3V Vout = 3V, Vcontrol = 5V, output current max. = 200mA. Is this ok?"
This is a common question so I will answer it myself in a REPLY post.
The customer's VCONTROL is high enough above VOUT that there is no dropout voltage concern for VCONTROL.
The image below shows how the specification for VIN Dropout Voltage from the datasheet Electrical…
