The ATLS250MA106 is an electronic module designed for driving diode lasers with up to 250mA extra low noise current. The output voltage is 1.5V to 4V when powered by a 5V power supply.
The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises. 

Ultra Low Noise: <100nA*
High Iout without Heat Sink: 250mA
High Iout Absolute Accuracy: <0.1%
High Iout Stability: <100ppm/°C
Separate Iout and Iout limit setting
Complete Shielding
Compact size
100 % Lead (Pb)-free and RoHS Compliant
DIP and SMT Packages Available
*Total RMS between 0.1 Hz to 100 KHz
