General Description
The AME8865 family of positive, CMOS linear regula-
tors, provide low dropout voltage (400mV @ 1.5A) and
excellent PSRR, thus making them ideal for power-sav-
ing systems. These rugged devices have both Thermal
Shutdown, and Current limit to prevent device failure un-
der the "Worst" of operating conditions.
The AME8865 is stable with an output capacitance of
4.7µF or larger.
