Note1:
Absolute maximum ratings indicate limits which when exceeded may result in damage to the component. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
Note 2:
Specified Min/Max limits are production tested or guaranteed through correlation based on statistical control methods. Measurements are
taken at constant junction temperature as close to ambient as possible using low duty pulse testing.
Note 3:
Dropout Voltage is defined as the measured Differential Voltage between input and output voltage, when the output voltage drops 2% below the nominal output
voltage as V
IN
is decreased, and approaches V
OUT
. Nominal output voltage is defined at V
IN
= V
