General Description
The AME8818 is a CMOS linear regulator. It operated from
2.5V to 5.5V input voltage and delivers up to 300mA output
current. The AME8818 provide low quiescent current (70uA
typ) low dropout voltage (230mV @ 300mA typ), and excel-
lent PSRR, thus marking them ideal for Data-Communica-
tions and battery applications.
The AME8818 provide over temperature and over current
protected functions. It is stable with an output capacitance of
1uF or larger.

Pin Description
Input voltage pin.
It should be decoupled with 1µF or greater capacitor.
Ground connection pin.
LDO voltage regulator output pin.
It should be decoupled with a 1µF or greater value low ESR ceramic capacitor.
The Enable pin normally floats high.
When pulled low, the PMOS pass transistors shut off, and all internal circuit are powered
down.
No Internal Connection
Bypass capacitor connection.
In AME8818BEEV and AME8818CEEV, IC will select internal circuit to improve ESR.
In AME8818AEEV, IC will select external circuit to improve ESR and AC ripple rejection.
