The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

In this article we introduce a new class of DC-to-DC converters, an example of which is the LTC3336. It only consumes about 65nA of current in standby mode, making it ideal for battery-operated ...
