Typical values refer to TJ=258C.
ELECTRICAL SPECIFICATIONS
Note 1: Low duty cycle pulse testing with Kelvin con-
nections is required in order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum dif-
ferential voltage between VIN and VOUT required to main-
tain regulation at VOUT. It is measured when the output
voltage drops 1% below its nominal value.
Note 3: Minimum load current is defined as the mini-
mum current required at the output in order for the out-
put voltage to maintain regulation. Typically the resistor
dividers are selected such that this current is automati-
cally maintained.
