STLA01 Datasheet, PDF (1/16 Pages) STMicroelectronics – 50 mA stand-alone linear LED driver

Features
■ Programmable LED current up to 50 mA with ±
5% accuracy
■ No external sense resistor
■ Constant current source
■ Supply voltage range from 3.75 V to 6 V
■ Single LED
■ 10 µA max supply current in shutdown mode
■ DFN6 (2 x 2 mm) package
Description
The STLA01 is a constant current LED driver.
No external sense resistor is required 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.
