1 Dropout voltage is defined as the input to output voltage differential when the input voltage is set to the nominal output voltage. Also Dropout
voltage does not apply to fixed output voltage options below 4V.
2All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC). Typical values are at T
A = 25°C.
Specifications subject to change without notice.
3Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, for a 1.0V
output voltage, the current limit is defined as the current that causes the output voltage to drop to 90% of 1V, or 0.9V.
