1. V_IN = 3.3 V, V_DDQ = 2.50 V, V_TT = 1.25 V (default values), C_DDQ = C_TT = 47 mF, T_A = 25°C unless otherwise specified.
2. he SHDN Logic High value is normally satisfied for full input voltage range by using a low leakage current (bellow 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. Changes in output
voltage due to heating effects must be taken into account separately. Load and line regulation values are guaranteed up to the maximum
power dissipation.
4. Dropout voltage is 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.
