LN9300 - Tiny Package Low Dropout Current Source

General Description

The LN9300 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs.

The LN9300 uses a internal resistor to set the bias current for four LEDs, which are matched to 3%.

Key Features

Ultra low 60mV dropout at 20mA.
3% High accuracy current matching.
20mA full scale current.
PWM brightness control.

Tiny Package Low Dropout Current Source LN9300 ■ General Description The LN9300 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The LN9300 uses a internal resistor to set the bias current for four LEDs, which are matched to 3%. The LN9300'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. The LN9300 requires a 60mV dropout at a 20mA load on each output to match the LED brightness.
