This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

As a response to a need for a simpler SMD package and higher current ratings, Semitec have now introduced the new S-series CRD range. The new SOT23 package offers constant current values from 0.1ma ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Diodes Incorporated's AL5809, offered in a robust two-terminal PowerDI®-123 package, provides an improved accuracy, cost-effective solution for constant-current linear driving of LEDs. Diodes ...
