Description

The GT2133 series of positive, linear regulators feature low quiescent current (30μA typ.) with low dropout voltage, making them ideal for battery applications.

The space-saving SOT-26 package is attractive for “Pocket” and “Hand Held” applications.

This rugged device has both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions.

An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and ground.

The GT2133 is stable with an output capacitance of 2.2μF or greater.
