CM2835
300mA CMOS LDO
GENERAL DESCRIPTION
The CM2835 family is a positive voltage linear regulator
developed utilizing CMOS technology featured low quiescent
current (30μA typ.), low dropout voltage, and high output
voltage accuracy, making them ideal for battery applications.
EN input connected to CMOS has low bias current. The
space-saving SOT-23 and SOT-89 package is attractive for
“Pocket” and “Hand Held” applications.
These rugged devices have both Thermal Shutdown, and
Current limit to prevent device failure under the “Worst” of
operating conditions.
The CM2835 is stable with a Low ESR output capacitance of
1.0μF or greater.
