1. The AAT2500B is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and cor-
relation with statistical process controls.
2. VDO is defined as VIN - VOUT when VOUT is 98% of nominal.
3. For VOUT < 2.1V, VDO = 1.8 - VOUT.
4. CIN = 10μF.
