The regulator is fully enabled when a logic-high is
applied to SHDN. The regulator enters shutdown when
a logic-low is applied to this input. During shutdown, the
output voltage falls to zero and the supply current is
reduced to 0.5 µA (max).
3.4
Connecting a low-value ceramic capacitor to Bypass
will further reduce output voltage noise and improve the
Power Supply Ripple Rejection (PSRR) performance
of the LDO. Typical values from 470 pF to 0.01 µF are
suggested. While smaller and larger values can be
used, these affect the speed at which the LDO output
voltage rises when input power is applied. The larger
the bypass capacitor, the slower the output voltage will
rise.
