Variable Voltage Power Supply Circuit We can improve our basic voltage regulator circuit a little more by connecting an Ammeter and a Voltmeter to the output terminals. These instruments will give a visual indication of both the current and voltage output from the variable voltage regulator. Voltage Regulator - Adjustable Output, Negative 1.5 A The LM337 is an adjustable 3?terminal negative voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of ?1.2 V to ?37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Linear and Switching Voltage Regulator Fundamentals Abstract This paper will enable the user to understand the operation of switching and linear voltage regulators. The most commonly used regulating modes will be covered. For linear regulators, the Standard, Low-Dropout, and Quasi Low-Dropout regulators will be covered (along with circuit A DC to DC convertor is a subset of a voltage regulator. Furthermore, to me, a DC-DC converter is more of an idea or a theory while a voltage regulator is an actual product 81.215.13.145 08:28, 4 June 2007 (UTC) Oppose. A DC-DC and a voltage regulator are very different devices, even if often they perform the same function. After an initial introduction in 5 V logic voltage regulator form, they have since expanded into other standard voltage levels spanning from less than 1 V to 24 V, handling output currents from as low as 25 mA (or less) to as high as 5 A (or more). For several good reasons, linear style IC voltage regulators have been valuable system 77006 How Step-Voltage Regulators Operate Author: EPSON Perfection 4990 Keywords: step-voltage regulator voltage regulator 32-step voltage regulator auto-booster voltage regulator auto-booster 32-step regulators Created Date: 5/8/2009 3:50:49 PM Richtek Technology Corporation is one of the world's leading analog IC companies. Our power management ICs such as voltage regulators, chargers, LED drivers, Flyback controllers, etc., are widely used in computers, consumer end products, network communication devices, large-size panel displays and other applications. simulate this circuit - Schematic created using CircuitLab. Since the regulator outputs are independent, the slight variance between 5V_BANK1 voltage and 5V_BANK2 voltage doesn't matter: as long as they are both within the 4.75V to 5.25V spec for each of the devices being powered. Therefore, the ideal voltage regulator could be considered a voltage source with a constant output voltage. However, in practice the IC regulator is better represented by the model shown in Figure 1-2. In this figure, the regulator is modeled as a voltage source with a positive output impedance (ZO). The Advantage of Transistor Series Voltage Regulator. The advantage of this circuit is that the changes in zener current are reduced by a factor ?. Hence, the effect of zener impedance is tremendously reduced and we get a more stabilised output. Disadvantage of Transistor Series Voltage Regulator Voltage regulator also has an extra circuit for short circuit protection, and current limiting circuit, over-voltage protection, and thermal shu
