NOTES:
Note 1: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential at
very low values of programmed output voltage, the minimum input supply voltage of 2V ( 2.3V over temperature) must be taken into account.
Note 2: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied excluding load or line regulation effect.
V
IN =VOUT + 1.5V, COUT = 10F, at IOUT = 10mA, TA = 25°C, unless otherwise specified. Limits in Boldface applies
over the full operating temperature range.
