General Description

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 current when enabled and 0.05uA when disabled.
