2. The ADJSD Logic High value is normally satisfied for full input voltage range by using a low leakage current (below 1 mA). Schottky diode
at ADJSD control pin.
3. Load and line regulation are measured at constant junction temperature by using pulse testing with a low duty cycle. For high current tests,
correlation method can be used. Changes in output voltage due to heating effects must be taken into account separately. Load and line
regulation values are guaranteed by design up to the maximum power dissipation.
4. Dropout voltage is the input to output voltage differential at which output voltage has dropped 100 mV from the nominal value obtained at
3.3 V input. It depends on load current and junction temperature. Guaranteed by design.
