VIN voltage tolerance +/- 5%. 4. Dropout voltage is the minimum input to output differential voltage needed to maintain VOUT to within 5% of no- minal value. This parameter is only specified for output voltages greater than or equal to 1.8V. 5. This electrical specification is guaranteed by design. |
