The STLA01 is a constant current LED driver. It has no external sense resistor and the DFN6 2 x 2 mm package makes it ideal for portable applications. The LED current limitation can be programmed using a single resistor connected between the PROG pin and GND. Using the enable pin the device can be put into shutdown mode, reducing the supply current to less than 10 µA.
The STLA01 is a constant current LED driver designed for portable applications. It operates with a supply voltage range from 3.75 V to 6 V and features a compact DFN6 (2 x 2 mm) package. The device requires no external sense resistor, as the LED current limitation is programmed using a single resistor connected between the PROG pin and GND.
