Basically, I'm building a device that powers a number of LEDs; each LED needs to have as consistent a power as possible (each eats 25mA at 3.3V) across the number of LEDs being lit up.
I'm using a L78L33C 3.3V regulator drawing from a 5V wall wart to supply power to the LEDs but I notice that each L78L33C has a load regulation of 60mV from 1mA to 100mA.
Since I need each LED to have extremely consistent brightness (+-20mV), I'm worried about the 60mV dropout.
Is there any way to ensure the power output for each LED stays exactly the same regardless of the number of LEDs I'm powering? Will putting multiple L78L33C in parallel with the LEDs help?
