AME8827
Low Dropout 1A CMOS Regulator
nGeneral Description
nTypical Application
The AME8827 family of positive, CMOS linear regula-
tors and provide low dropout voltage (340mV @ 1A) and
excellent PSRR, thus making them ideal for power-sav-
ing systems. These rugged devices have both Thermal
Shutdown, and Current limit to prevent device failure un-
der the "Worst" of operating conditions.

AME8827
Low Dropout 1A CMOS Regulator
nDetailed Description
The AME8827 is low-dropout; low quiescent current
linear regulator designed for motherboard, notebook and
LCD monitor applications. The output voltage range from
1.2V to 3.6V, and can drive 1A loading current.
Capacitor Selection and Regulator Stability
Use 1mF for input capacitor and 4.7mFor great for out-
put capacitor on the AME8827. Larger input capacitor
value and low ESR provide better supply noise rejection
and improve line transient response. To reduce output
noise and load transient response, use output capacitor
greater than 4.7mF.
Calculating the Maximum Output Power
The maximum output power of the AME8827 is limited
by the maximum power dissipation of the package. By
calculation the power dissipation of the package as a
function of the input voltage, output voltage and output
current, the maximum input voltage can be obtained. The
maximum power dissipation should not exceed the
package's maximum power rating.
PMAX = ( VIN.MAX - VOUT ) x IOUT
Where:
VIN.MAX = maximum input voltage
PMAX = maximum power dissipation of the package
