Reference Bypass Input. Connecting an
optional 470 pF to this input further reduces
output noise.
Shutdown Control Input. The regulator is fully
enabled when a logic high is applied to this
input. The regulator enters shutdown when a
logic low is applied to this input. During shut-
down, regulator output voltage falls to zero,
RESET output remains valid and supply cur-
rent is reduced to 30 µA (typ.).
