natlinear LN9306
The LN9306 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The LN9306 uses a internal resistor to set the bias current for six LEDs, which are matched to 3%. The LN9306's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency.| Part No. | LN9306 |

GENERAL DESCRIPTION
The LN9306 requires a 60mV dropout at a 20mA load on each output to match the LED brightness. The LN9306 is suitable for single cell Li-ion bat-tery power device that using low forward voltage white LEDs. The white LEDs can be powered directly from battery without extra external components. This takes an advantage of highest efficiency and creates no EMI problem.● Ordering Information LN9306 ①②③ (Eg: LN9306SRG) Item ① ② ③ Symbol S D * R L N P G
