Ultra low-dropout regulator, low noise, 200 mA
9. Dynamic behavior
All results described in
Section 9
are based on measurements of types LD6806CX4xxx
and LD6806Fxxx from the LD6806 product series.
9.1 Dropout
The dropout voltage is defined as the smallest input to output voltage difference at a
specified load current when the regulator operates within its linear region with the pass
transistor functioning simply as a resistor. This means that the input voltage is below the
nominal output voltage value.
A small dropout voltage guarantees lower power consumption and maximizes efficiency.
