The AAT1153 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. VIN should be not less than VOUT + VDROPOUT, where VDROPOUT = IOUT x (RDS(ON)PMOS + ESRINDUCTOR), typically VDROPOUT = 0.3V. 3. The regulated feedback voltage is tested in an internal test mode that connects VFB to the output of the error amplifier. |
