Electrical Characteristics
VIN(3)=VOUT + 0.5V or 1.8V (whichever is higher). TA=-40°C to +85°C, test circuit is Figure 1, typical values are at
TA=25°C, ILOAD=1 mA, VEN=VIN, unless otherwise noted.

Note:
3. VIN voltage tolerance +/- 5%.
4. Dropout voltage is the minimum input to output differential voltage needed to maintain VOUT to within 5% of
nominal value. This parameter is only specified for output voltages greater than or equal to 1.8V.
5. This electrical specification is guaranteed by design.
