DESCRIPTION
The SS6721/6721D are 150/300mA low dropout
linear regulators. The superior characteristics of the
SS6721 and SS6721D include zero base-current
loss, very low dropout voltage, and 1% accuracy
of output voltage. Typical ground current is
approximately 55µA, across the load range
from zero to maximum. With an output current
of 100mA, the dropout voltage of the SS6721
and SS6721D is substantially lower (130mV for
SS6721-50 and SS6721D-50, and 180mV for the
SS6721-33 and SS6721D-33) when compared
with a bipolar device. Built-in output current and
thermal limiting provide maximum protection of the
SS6721 and SS6721D against fault conditions.
The SS6721 and SS6721D are available in
the popular SOT-89 and TO-92 packages.
