CM2838
300mA LOW ESR CMOS LDO WITH ENABLE
GENERAL DESCRIPTION
FEATURES
The CM2838 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-23-5 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.
In application requiring a low noise, regulated supply, place a
1000pF capacitor between Bypass and Ground.
