Enable
If any one of the three low-dropout linear regulators
(LDOs) is enabled, the internal 1.25V reference powers
up. Therefore, all three LDOs must be disabled to shut
down the internal reference, reducing the supply cur-
rent to 0.01μA.
Pull EN_ low to enter shutdown. When any one of the
linear regulators is shutdown, the corresponding
MAX8890 output disconnects from the corresponding
input, and the output discharges through an internal
5k ? resistor. The capacitance and load determine the
rate at which V OUT _ decays. Do not leave EN_ floating.
Connect EN_ to IN_ for normal operation. EN_ can be
pulled as high as 6V, regardless of the input and output
voltages.
Thermal-Overload Protection
Thermal-overload protection limits the MAX8890 ’ s total
power dissipation in the event of fault conditions. Each
linear regulator has its own thermal-shutdown circuitry.
