General Description
The AME8853 family of positive, CMOS linear regula-
tors provide low dropout voltage(220mV@300mA), 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.

Pin Description
Input voltage pin; should be decoupled with 1 F or greater
capacitor.
Ground connection pin.
Enable pin, Active “high". When pulled “low”, the PMOS pass
transistor turns off, current consuming less than 1 A. When EN
pin float outside, it’s weakly pulled high form internal MOS.
No connection.
LDO voltage regulator output pin; should be decoupled with
a 1.0 F or greater value low ESR ceramic capacitor.
No connection.
