T6311A - Constant-Current White LED Bias Supply
The T6311A low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs.
The T6311A uses a single resistor to set the bias current for four LEDs, which are matched to 0.3%.
The T6311A consumes only 40uA of supply curr
