The AAT2504 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. V DO is defined as VIN - VOUT when VOUT is 98% of nominal. 3. For V OUT < 1.5V, VDO = 1.8 - VOUT. 4. C IN = 10µF. |
