significantly improved efficiency. The RT9300A/B requires a 60/45mV dropout at a 20/15mA load on each output to match t.
The RT9300A/B low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The RT9300A/B uses a internal resistor to set the bias current for four LEDs, which are mat.
