Unless otherwise specified, these specifications apply over Cin=1

µF, Cout=10µF, and Tj=0 to 150!C.

Typical values refer to Tj=25!C.

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.
