Note : Load and line regulation are specified at constant junction temperature.

Change in Vo due to heating effects must be taken into account separately. Pulse testing with low duty is used.

TYPICAL APPLICATION (PROGRAMMABLE REGULATOR)

Ci is required when regulator is located an appreciable distance from power supply filter.

Co is not needed for stability, however, in the range of 1

㎌ to 100㎌ of aluminum or tantalum

electrolytic are commonly used to provide improved output impedance and rejection of transients.
