ILC7083/ILC7084
Electrical Characteristics ILC7083/ILC7084
Unless otherwise specified, all limits are at TA=25°C; VIN = VOUT(NOM) +1V, IOUT = 1mA, COUT = 1µF, VON/OFF = 2V.
Boldface type denotes specifications which apply over the specified operating temperature range.

Notes:
1. 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.
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.
3. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the nominal value measured
with an IV differential.
4. Guaranteed by design.
