I just bought 10 pcs of LDL1117S33R which i plan to use them to power 3.3V modules form a 4V regulated source.
According to the data sheet the typical dropout is 350mV and max is 600mV @1.2A. My module consumes less than 500mA, so i expect to have enough margin with a Vin of 4V to get 3.3V at the ouput. But the module doesnt boot at 4V input.
When measured the dropuout is 1V - 1.1V. Did anybody face this problem?
