AME8861
600mA CMOS LDO
n General Description
The AME8861 family of positive, linear
regulators feature low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-25 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 applications requiring a low noise, regulated supply, place a 1000 pF capacitor between Bypass and ground. The AME8861 is stable with an output capacitance of 2.2µF or greater.
