50/100mA SOT-23 CMOS RF LDO™ Regulators
Electrical Characteristics ILC7080/81AIM5 (cont.)
Unless otherwise specified, all limits are TA = 25°C; VIN = VOUT(NOM) + 1V, IOUT = 1mA, COUT = 1µF, VON/OFF = 2V.
Boldface limits apply over the operating temperature range. (Note 2)

Note 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.
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 input to output differential voltage at which the output voltage drops 2% below the nominal value measured with a 1V differential.
Note 4: Guaranteed by design
Note 5: The device’s shutdown pin includes a 2MW internal pull down resistor connected to ground.
