AME
High PSRR, Low Noise, 600mA
CMOS Regulator
AME8855
n General Description
n Typical Application
The AME8855 family of positive, CMOS linear regula-
tors provide low dropout voltage(420mV@600mA), low
quiescent current, and low noise CMOS LDO. These
rugged devices have both Thermal Shutdown, and Cur-
rent limit to prevent device failure under the "Worst" of
operating conditions.
