All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Typical values are at T
A
= 25°C.
2
Guaranteed by design.
3
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.
4
All LX (switch) node characteristics are guaranteed only when the LX1 pin and LX2 pin are tied together.
5
These specifications are guaranteed from −40°C to +85°C.
