Figure 2 shows the preferred method for the bypass
and output capacitor connections. For low output
noise and highest possible power supply ripple
rejection performance, it is critical to connect the
bypass and output capacitor directly to the LDO reg-
ulator ground pin. This method will eliminate any
load noise or ripple current feedback through the
LDO regulator.
