• If my system is specified to operate from –55° to 125°C, how much will my output voltage vary from the ideal? • My output voltage will be within ±0.1% of ideal if I use ±0.1% resistors, right?

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...

Applications sometimes require the generation of a voltage that is below the reference rail. Many design engineers would just use a second regulator to generate this voltage. However, a simple change ...

We use batteries to supply power in several projects. The chemicals contained in the battery are converted into an electrical current, which in turn makes the battery contain the potential energy.

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
