GENERAL DESCRIPTION

The SP7121 LED driver provides a simple solution for a matched current source for any color common

cathode LEDs. The common cathode connection allows the user to increase the LED power dissipation

by having the cathodes heat sinked to the ground plane of the circuit board. The SP7121 output current

value is set by an external resistor. At shutdown mode (EN pin is LOW), the supply current drops

to .04µA typical. The SP7121 driver is available in a small footprint 6-pin SOT23-6 package.
