Current Limiter for LED
POSISTORr is an effective current limit solution based
on LED's allowable current and temperature
characteristic.
(1) LED lighting instruments
(2) LED backlight of flat displays
(1) Higher LED brightness versus a fixed resistor. LED
(2) LED lifetime may be extended due to the current
(3) Small 0805 package allows the POSISTORr to be

and resistance value. Review the protective threshold
current range based on the operating current and
temperature of the LED.
