ELECTRICAL SPECIFICATIONS

8C.

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-

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 it automatically main-

tains this current.
