Low-dropout regulators, low noise, 150 mA
9. Dynamic behavior
9.1 Power Supply Rejection Ratio (PSRR)
PSRR stands for the capability of the regulator to suppress unwanted signals on the input
voltage like noise or ripples.
for all frequencies
9.2 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 as a plain resistor. This means that the input voltage is below the
nominal output voltage value.
A small dropout voltage guaranties lower power consumption and efficiency maximization.
