GT2133

ISSUED DATE :2006/01/26 REVISED DATE : GT2133 Description C M O S P o s i t i v e Vo l t a g e R eg u l a t o r The GT2133 series of positive, linear regulators feature low quiescent current (30 A 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 2.2 F or greater.
