Typical values refer to Tj=25!C.

ELECTRICAL SPECIFICATIONS

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.

Note 2: Dropout voltage is defined as the minimum differential voltage between Vin and Vout required to maintain

regulation at Vout. It is measured when the output voltage drops 1% below its nominal value.
