LN9305 Overview
The LN9305 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The LN9305 uses a internal resistor to set the bias current for five LEDs, which are matched to 3%. The LN9305's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some...
