1. The AAT3242 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and correla-

tion with statistical process controls.

2. V_DOis defined as V_IN- V_OUTwhen V_OUTis 98% of nominal.

3. For V_OUT< 2.3V, V_DO= 2.5 - V_OUT

4. C_IN= 10µF.

5. To calculate minimum input voltage, use the following equation: V_IN(MIN)= V_OUT(MAX)+ V_DO(MAX)as long as V_IN≥ 2.5V.
