AME8855 - Analog Microelectronics

AME8855 600mA CMOS Regulator

The AME8855 family of positive, CMOS linear regulators provide low dropout voltage(420mV@600mA), low quiescent current, and low noise CMOS LDO. These rugged devices have both Thermal Shutdown, and Current limit to prevent device failure under the "Worst" of operating conditions.
