NOTE1: Dropout voltage is defined as the input to output differential at which the output voltage drops to 99%
of its nominal value.
NOTE2: V _IN=V_OUT(NOMINAL)+1V; for example, V_IN=4.3V for a 3.3V regulator. Employ pulse-testing procedures to
minimize temperature rise.
NOTE3: Ground pin current is the regulator quiescent current. The total current drawn from the source is the
sum of the load and ground currents.
NOTE4: Thermal regulation is defined as the change in the output voltage at a time T after a change in power
dissipation is applied, excluding load or line regulation effects.
NOTE5: V _EN )0.8V and V _IN )16V, V _OUT= 0.
NOTE6: Maximum positive supply voltage of 20V must be of limited duration ( <100ms) and duty cycle (<1%).
The maximum continuous supply voltage is 16V.
NOTE7: V _REF )V _OUT )(V _IN-1), 2.5V )V _IN )16V, 10 mA )I _C )I _FL, T_J < T_JMAX.
