3. LM317 - Wikipedia

   en.wikipedia.org/wiki/LM317

   LM317 with heat sink. The LM317 is an adjustable positive linear voltage regulator.It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1]The LM337 is the negative complement to the LM317, which regulates voltages below a reference.

4. Regulated power supply - Wikipedia

   en.wikipedia.org/wiki/Regulated_power_supply

   A bench power supply usually refers to a power supply capable of supplying a variety of output voltages useful for BE (bench testing) electronic circuits, possibly with continuous variation of the output voltage, or just some preset voltages. Some have multiple selectable ranges of current/voltage limits which tend to be anti-proportional. [2 ...

5. 78xx - Wikipedia

   en.wikipedia.org/wiki/78xx

   The 78xx line are positive voltage regulators: they produce a voltage that is positive relative to a common ground. There is a related line of 79xx devices which are complementary negative voltage regulators. 78xx and 79xx ICs can be used in combination to provide positive and negative supply voltages in the same circuit.

6. Voltage regulator - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator

   The ferroresonant transformer, ferroresonant regulator or constant-voltage transformer is a type of saturating transformer used as a voltage regulator. These transformers use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output voltage with a varying input current or varying load.

7. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

8. Linear regulator - Wikipedia

   en.wikipedia.org/wiki/Linear_regulator

   Series regulators are the more common form; they are more efficient than shunt designs. The series regulator works by providing a path from the supply voltage to the load through a variable resistance, usually a transistor (in this role it is usually termed the series pass transistor); it is in the "top half" of the voltage divider - the bottom half being the load.

9. Crowbar (circuit) - Wikipedia

   en.wikipedia.org/wiki/Crowbar_(circuit)

   In the following example crowbar circuit, the LM431 adjustable zener regulator controls the gate of the TRIAC. The resistor divider of R 1 and R 2 provide the reference voltage for the LM431. The divider is set so that during normal operating conditions, the voltage across R 2 is slightly lower than V REF of the LM431. Since this voltage is ...
