AME8801/8812/8840 |
300mA CMOS LDO |
|

|
|
n General Description
The AME8801/8840 family of positive, linear regulators feature low quiescent current (30μA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-23-5 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.
In applications requiring a low noise, regulated supply, place a 1000 pF capacitor between Bypass and Ground.
The AME8801 is stable with an output capacitance of 2.2μF or greater.
