AT rated input (DC12V) and rated output (1.2V) Ta=25C.
Output voltage is adjusted to the minimum when TRM is opened.
Ripple and ripple noise is measured by using measuring board with ceramic capacitor at 50mm from output pin.
Drift is the change in DC output for an eight hour period after a half - hour warm - up at 25C, with the input voltage held.
Output voltage setting is added line regulation and load regulation and temperature regulation used resistance of the 0.5% tolerance.
