3. Test Condition: V
4. Limits established by characterization and are not production tested.
5. The dropout voltage is defined as minimum amount VIN must exceed a desired VOUT operating point. V
6. The input voltage VCC must be higher than VIN_LDO or the LDO will not function.
7. Specifications at -40°C to +85°C are guaranteed by +25°C test with margin limits.
