http://www.powerguru.org/changing-the-output-voltage-of-a-switching-regulator-on-the-fly/ There are many different ways to change the output voltage Applications that require the output voltage of a power supply to change dynamically come from a wide…

Many applications require current sources rather than voltage sources. When you need a high-current source, using a linear regulator is inadvisable, because of the high power dissipation in the series resistor. To solve the wasted-power problem, you…

LDO Regulator High accuracy voltage regulator Vout = 2.5V * (1 + ( 5.6 / 6.8 ) ) = 4.55V Recently the author had to adapt  a standard circuit configuration  (which often uses an npn bipolar) so as to operate as a low-dropout (LDO) regulator. The circ…

The circuit in Figure 1 delivers programming voltages to an EEPROM under the control of an external DAC (not shown). You can replace the DAC with a potentiometer to create a general-purpose power supply operating from 12V and able to deliver a variab…
