APU1160

3/5

This pin is the positive side of the reference which allows remote load sensing to achieve

excellent load regulation.

The output of the regulator. A minimum of 10

mF capacitor must be connected from this

pin to ground to insure stability.

This pin is the supply pin for the internal control circuitry as well as the base drive for the

regulate. (See specifications)

The input pin of the regulator. Typically a large storage capacitor is connected from this

pin to ground to insure that the input voltage does not sag below the minimum dropout

order for the device to regulate. (See specifications)

Note 1: Low duty cycle pulse testing with Kelvin con-

nections are required in order to maintain accurate data.

Note 2: Dropout voltage is defined as the minimum dif-

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.
