GENERAL DESCRIPTION
The CM2843 family is positive, linear regulators featured low
quiescent current (30μA typ.) with low dropout voltage,
making them ideal for battery applications. The space-saving
SOT-23-5 package is attractive for “Pocket” and “Hard Held”
applications.
These rugged devices have both Thermal Shutdown, and
Current Fold-back to prevent device failure under the “Worst”
of operating conditions.
An additional feature is a “Power Good” detector, which pulls
low when the output is out of regulation.
The CM2843 is stable with an output capacitance of 2.2μF or
greater.
