AME8821 n General Description 250mA Hi-PSRR, Low-Quiescent LDO with In-Rush Current Control For USB Application n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets The AME8821 family of positive, linear regulators feature low quiescent current (17µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-25/TSOT-25 packages are attractive for “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 a low noise regulated supply.
