CM2831

300mA CMOS LDO W

ITH

NABLE

GENERAL DESCRIPTION

The CM2831 family is a positive voltage linear regulator

developed utilizing CMOS technology featured low quiescent

current (30

A 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.

The CM2831 is stable with an output capacitance of 2.2

F or

greater.
