Note 1: Low duty cycle pulse testing with Kelvin connections are required in order to maintain accurate data
Note 2: Dropout Voltage is defined as the minimum differential voltage between VI and VO required to mantain regulation at VO. It is measured
when the output voltage drops 1% below its nominal value.
Note 3: Transient response is defined with a step change in load from 10mA to 500mA as the time from the load step until the output voltage
reaches it’s minimum value.
Note 4: Minimum load current is defined as the minimum current required at the output in order for the output voltage to maintain regulation.
Note 5: Guaranteed by design, not tested in production.
