The ATLS200MA103 is an electronic module designed for driving diode lasers with up to 200mA low noise current. When the maximum power consumed by the controller is maintained to <1W, it does not require a heat sink to operate. The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises. 

Ultra Low Noise: ≤2.5µVp-p @0.1Hz to 10Hz 
High Current without Heat Sink: 200mA 
High Absolute Accuracy: <0.1% 
High Stability: <100ppm/°C 
Programmable Current Limit 
Complete Shielding 
Compact Size 
100 % Lead (Pb)-free and RoHS Compliant 
DIP and SMT Packages Available
