Definition

Stability is defined as the percent change in output voltage per unit of time, with all other operating conditions constant.

Test Setup

The test setup for stability is the same as for temperature coefficient. A range of temperatures are also used. The difference in the two tests is that for stability measurements the test conditions are held for a specific time at a constant temperature rather than for just a stable output to occur. Standard time periods are per 10 minutes, 1 hour, or 8 hours.

Test Method

Set input voltage, output voltage, load, and temperature to desired levels. Monitor output voltage continuously, preferably on a strip chart recorder.
