CM2831
300mA CMOS LDO WITH ENABLE
GENERAL DESCRIPTION
FEATURES
The CM2831 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 Fold-back 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.
