CM2830 Datasheet, PDF (1/16 Pages) List of Unclassifed Manufacturers – 300mA CMOS LDO

CM2830/CM2830A
300mA CMOS LDO
GENERAL DESCRIPTION
FEATURES
The CM2830/CM2830A family is a positive voltage linear
regulator developed utilizing CMOS technology featured low
quiescent current (30 µ A typ.), low dropout voltage, and high
output voltage accuracy. Built-in low on-resistance transistor
provides low dropout voltage and large output current. A
2.2 µ F or greater can be used as an output capacitor.
The SOT-23-3, SOT-23-5, and TO-92 miniaturized package
and the SOT-89 package are recommended for configuring
portable devices and large current application, respectively.
These robust devices are designed to prevent device failure
under the worst operation condition with both Thermal
Shutdown and Current Fold-back.
