Ⅰ、General Description:
The AME8851 family of positive, CMOS linear regulators, provide low dropout voltage (400mV @ 1.5A)
and excellent PSRR, thus making them ideal for power-saving systems. These rugged devices have both
Thermal Shutdown, and Current limit to prevent device failure under the "Worst" of operating conditions.
The AME8851 is stable with an output capacitance of 4.7µF or larger.
