AME8826

AME, Inc. www.DataSheet4U.com AME8826 1.55A CMOS LDO ! General Description The AME8826 family of positive, linear regulators feature low quiescent current (45µA typ.) with low dropout voltage, making them ideal for battery applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground. The AME8826 is stable with an output capacitance of 4.7µF or greater. !
