Unless otherwise specified. all limits are at 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

an IV differential.

Note 4: Guaranteed by design

Note5 : The device’s shutdown pin includes a 2M

Ω internal pulldown resistor connected to ground.
