AME8816  
1.5A CMOS LDO  
n General Description  
The AME8816 family of positive, linear regulators fea-  
ture low quiescent current (45µA typ.) with low dropout  
voltage, making them ideal for battery 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 1000pF capacitor between Bypass and Ground.  
The AME8816 is stable with an output capacitance of  
4.7µF or greater.
