Ultra low-dropout regulator, low noise, 200 mA
9.4 Noise
Output noise voltage of an LDO circuit is given as noise density or RMS output noise
voltage over a defined range of frequencies (10 Hz to 100 kHz). Permanent conditions are
a constant output current and a ripple-free input voltage. The output noise voltage is
generated by the LDO regulator.
