The AME8821 family of posiTIve, linear regulators featurelow quiescent current (17mA typ.) with low dropoutvoltage, making them ideal for battery applicaTIons. Thespace-saving SOT-25/TSOT-25 packages are attracTIvefor “Pocket” and “Hand Held”applicaTIons.These rugged devices have both Thermal Shutdown,and Current Limitation to prevent device failure under the“Worst” operating conditions. In application requires alow noise regulated supply. The AME8821 family usesthe SR pin to program the output voltage’s slew rate tocontrol the in-rush current. This is specifically used inthe USB application where large load capacitance ispresent at start-up.The AME8821 also features a logic-enabled sleep modeto shutdown the regulator, reducing quiescent current to1mA typical at TA= 25oC.The AME8821 is stable with an output capacitance of4.7mF or larger.
