RT9300A Product details

Description

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 an internal resistor to set the bias current for four LEDs, which are matched to 5%.

Features

z Low 60/45mV Dropout at 20/15mA z 5% LED Current Matching z Simple LED Brightness Control z 2.5V to 5.5V Supply Voltage Range z Thermal Shutdown Protection z RoHS Compliant and 100% Lead (Pb)-Free.
