GENERAL DESCRIPTION The SGM3123 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. It is optimized for low power keypad and portable backlighting applications. The SGM3123 uses an internal resistor to set the bias current for four LEDs, which are matched to ±5%. The SGM3123's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout vo.
