All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Typical values are at T A = 25°C.
Guaranteed by design.
The ADP2105/ADP2106/ADP2107 line regulation was measured in a servo loop on the automated test equipment that adjusts the feedback voltage to achieve a
specific COMP voltage.
All LX (switch) node characteristics are guaranteed only when the LX1 pin and LX2 pin are tied together.
These specifications are guaranteed from ?40°C to +85°C.
