AME
Low Dropout
300mA CMOS Regulator
AME8818
n 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 (70µA
typ) low dropout voltage (230mV @ 300mA typ), and excellent PSRR, thus marking them ideal for Data-Communications and battery applications.
The AME8818 provide over temperature and over current
protected functions. It is stable with an output capacitance of
1µF or larger.

AME8818
n Detailed Description
The AME8818 is low-dropout, low quiescent-current linear
regulator designed primarily for battery-powered applications.
It is available with present output voltage ranging from 1.2V
to 4.5V, and can supply loads up to 300mA.
n Shutdown Mode
The AME8818 has enable-control-pin. Drive EN low to shutdown OUT. Drive EN to shutdown the entire chip, reducing
supply current to 5µA. Connected EN to logic-high or IN for
normal operation.
n Circuit Limit
The AME8818 contains current limiters which monitor and
control the pass transistor's Gate voltage, limiting the guaranteed maximum output current to 330mA minimum. The
output can be shorted to ground for an indefinite time without
damaging the part.
Low Dropout
300mA CMOS Regulator
n Capacitor Selection and
Regulator Stability
Use a 1µF capacitor on the AME8818 input and a
1µF capacitor on the OUT. Larger input capacitor values and lower ESR provide better supply noise rejection and line transient response. To reduce output
noise and improve load transient voltage dips, use
larger output capacitors up to 4.7µF. For stable operation over the full temperature range with load currents up to 300mA, input and output capacitors should
be a minimum of 1µF by X7R.
Note that some ceramic dielectrics large capacitance
and ESR variation with temperature. With dielectrics
such as Z5U and Y5V, it may be necessary to use
2.2µF or more for up to 300mA load current to ensure
stability at temperatures below -10oC. With X7R or
X5R dielectrics, 1µF is sufficient at all operating temperatures. These regulators are optimized for ceramic
capacitors. Tantalum capacitors are not recommended.
Bypass capacitor can be in between 0.1µF~0.001µF.
A larger capacitor improves AC ripple rejection, but
also make the output come up slowly.
n Thermal-Overload Protection
n Adjustable Version
Thermal-overload protection limits total power dissipation
in the AME8818. When the junction temperature arrive TJ =
160oC approximately, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC
to cool.
The adjustable version uses external feedback resistors to generate an output voltage anywhere from
0.98V to 4.5V. VADJ is trimmed to 0.98V and VOUT is
given by the equation:
VOUT = VADJ ( 1 + R1 / R2 )
n PSRR and Operation from
sources Other than Batteries
The AME8818 is designed to deliver low-dropout voltage
and low quiescent currents in battery-powered system.
Power-supply rejection ratio is 60dB (Typ.) at 1KHz. When
operating from sources other than betteries, PSRR and transient response can be improved by increasing input, output
and bypass capacitors(see PSRR vs Frequency Curve).
Rev.D.06
Feedback resistors R1 and R2 should be high enough
to keep quiescent current low, but increasing R1 + R2
will reduce stability. In general, R1 and R2 in the 10's
of kΩ will produce adequate stability, given reasonable layout precautions. To improve stability characteristics, keep parasitics on the ADJ pin to a minimum, and lower R1 and R2 values.
