AME8844
750mA CMOS LDO
n General Description
The AME8844 family of positive, linear regulators feature low quiescent current (45A typ.) with low dropout voltage, making them ideal for battery applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" operating conditions. An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation. The AME8844 is stable with an output capacitance of 4.7F or greater.
