ATLS250MA106 is a constant current laser diode driver with 250mA low noise current. The noise is very low, 2μVP-P at the frequency of 0.1Hz to 10Hz. There is no need for heat sinks.
When the power supply is 5V, the output voltage is from 1.5V to 4V. This laser driver comes with an internal temperature compensation network so as to maintain the output current to be the same even as the laser driver temperature rises. The laser driver will shut down by itself when the temperature exceeds 120°C, which can prevent the laser driver from being damaged by over heat.
There are two packages for the laser driver, DIP package and SMT package. The SMT package laser driver can only be soldered and it's not convenient to remove it. The DIP package can be removed easily, but the stability of the system is not as good as the SMT package. ATLS250MA106D is for DIP package and ATLS250MA106S is for SMT package. Both DIP and SMT laser drivers are packaged in a 6-sided metal enclosure for avoiding EMIs.
