The MAX15029/MAX15030 low-dropout linear regula-
tors operate from input voltages as low as 1.425V and
deliver up to 500mA of continuous output current with a
maximum dropout voltage of only 150mV.
The MAX15030 operates with an input voltage as low
as 1.425V if the bias voltage (V
available. The power is applied at IN while the control
is provided through BIAS input. The current drawn by
BIAS is negligible when the LDO goes into the shut-
down. This feature is especially useful in automotive

applications where the BIAS input is derived from an
always-on LDO that expects to provide minimal power
during the key-off condition.
The pMOS output stage can be driven from input volt-
ages down to +1.425V without sacrificing stability or
transient performance. The output voltage of all the
regulators is adjustable from 0.5V to V
accurate over load and line variations, from -40°C to
+125°C. Since these regulators have a pMOS output
device, supply current is not a significant function of
load or input headroom.
