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.
The CM2838 is stable with a Low ESR output capacitance of
1.0µF or greater.
Very Low Dropout Voltage
Low Current Consumption: Typ. 30µA, Max. 35µA
Output Voltage: 1.8V, 2.5V, 2.8V, 3.0V, and 3.3V
High Accuracy Output Voltage: +/- 1.5%
Guaranteed 300mA Output
Input Range up to 7.0V
Thermal Shutdown
Current Limiting
