1. The AAT2506 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured
by design, characterization, and correlation with statistical process controls.
2. To calculate the minimum LDO input voltage, use the following equation: V
IN(MIN)
= V
OUT(MAX)
+ V
DO(MAX)
, as long as V
IN
≥
2.5V.
3. For V
OUT
<2.1V, V
DO
= 2.5 - V
OUT
.
4. V
DO
is defined as V
IN
- V
OUT
when V
OUT
is 98% of nominal.
