CM2841 Datasheet, PDF (1/11 Pages) List of Unclassifed Manufacturers – 150mA CMOS LDO WITH EN PG

CM2841
150mA CMOS LDO WITH EN & PG
GENERAL DESCRIPTION
FEATURES
The CM2841 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.
