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…

A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the resistance every 2°C over a range of –40 to +102°C,…

High accuracy voltage regulator Good morning everybody, I want to make a accurate voltage regulator based on the Basic Stamp.Total range 0-10 V and a resolution of eg 5 mV. So this means 2000 steps.Maximum current around 250 mA. I tried to do somethi…

The classic LM317 adjustable-output linear voltage regulator offers a relatively high, if package-dependent, current-handling capability. In addition, the LM317 features current limiting and thermal-overload protection. With the addition of a few com…
