AME, Inc. AME8841 n General Description The AME8841 linear regulator features low quiescent current (30µA typ.) with low dropout voltage, making it ideal for battery applications. The space-saving SO-8 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. EN 600mA CMOS LDO n Functional Block Diagram IN Overcurrent Shutdown OUT Thermal Shutdown The AME8841 is stable with an output capacitance of 2.2µF or greater.
