Two of the time effects used in assessing the unprogrammed output deviation. Noise is the aperiodic random component while ripple is the periodic component harmonically related to the source frequency. Generally, “noise” is distinguished from”signal” by its unwanted, unappreciated character.

(1) 4% accuracy for factory set current limit. (2) 10% of current limit setting value foldback. (3) Ripple and noise = 1.5 x indicated values for Ta = -10°C to 0°C. Values shown are satisfied for 0 to 100% load, 0 to 65°C. measuring bandwidth ≤ 100MHz.
(4) Shutdown upon fault condition. After disconnecting a-c input, remove the fault, wait about 40 seconds, then reconnect a-c input. (5) Output disconnected for output current > 1.45 x rated current limit. Output limited to a negative Schottky diode drop.
