), 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 CM2833 is stable with an output capacitance of 2.
2µF or greater.
