... • When a capacitor is already charged, it is allowed to discharge through a resistance R. – When the switch S is closed, the voltage across the resistor at any instant equals that across the capacitor. Thus IR=Q/C. – The rate at which the charge leaves the capacitor equals the negative the current f ...

Datasheet - DE-SWADJ
... The DE-SWADJ is designed to be the easiest possible way to utilize the benefits of switchmode power when you need an unusual or easily changed voltage. The DE-SWADJ family is pin-compatible with the common 78XX family of linear voltage regulators, and can step down to 1.25v to 13v with no external c ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
