AME8820

www.DataSheet4U.com AME, Inc. High PSRR, CSP, 150mA CMOS LDO n Functional Block Diagram IN Overcurrent Shutdown AME8820 n General Description The AME8820 family of positive, linear regulators feature low quiescent current (30µA typ.) low dropout voltage and excellent PSRR, thus making them ideal for Telecommunications and other battery applications. The ultra-small CSP package is attractive for "Pocket" and "Hand Held" applications. These rugged devices have both Thermal Shutdown, and Current limit to prevent device failure under the Worst operating conditions. The AME8820 is stable with an output capacitance of 1µF or larger.
