General Description
The AME8852 family of positive, CMOS linear regula-
tors provide low dropout voltage(110mV@150mA), 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.

Enable pin, Active “high". When pulled “low”, the
PMOS pass transistor turns off, current consuming
less than 1µA. When EN pin floating outside, it is
pulled low by internal small current source.
