Note 5 : Low duty cycle pulse test with Kelvin connections are required to maintain data accuracy .

Note 6 : Dropout voltage is defined as the minimum difference between VIN and VOUT required to maintain 1% VOUT

regulation.

Note 7 : Minimum load current is defined as the minimum current required at the output to maintain VOUT regulation.

Unless otherwise noted , these specifications apply over C

IN = 10µF, CCNTL = 1µF, COUT = 10µF, and TA = 0 to 70°C.

Typical values refer to T

A = 25°C. VOUT = VSENSE.
