AME8819
n General Description
The AME8819 is a CMOS linear regulator. It operated from 2.5V to 5.5V input voltage and delivers up to 300mA output current. The AME8819 provide low quiescent current (70uA typ) low dropout voltage (Vout=3.3V, 540mV @ 600mA typ), and excellent PSRR, thus marking them ideal for Data-Communications and battery applications. The AME8819 provide over temperature and over current protected functions. It is stable with an output capacitance of 2.2uF or larger.

n Detailed Description
The AME8819 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 3.6V, and can supply loads up to 600mA.
Low Dropout 600mA CMOS Regulator
n Capacitor Selection and Regulator Stability
Use 1uF 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 4.7uF. For stable operation over the full temperature range with load currents up to 600mA, input and output capacitors should be a minimum of 2.2uF 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 4.7uF or more for up to 600mA load current to ensure stability at temperatures below -10oC. With X7R or X5R dielectrics, 2.2uF is sufficient at all operating temperatures. These regulators are optimized for ceramic capacitors. Tantalum capacitors are not recommended.
n Circuit Limit
The AME8819 contains current limiters which monitor and control the pass transistor's Gate voltage, limiting the guaranteed maximum output current to 650mA minimum. The output can be shorted to ground for an indefinite time without damaging the part.
n Thermal-Overload Protection
Thermal-overload protection limits total power dissipation in the AME8819. 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.
n PSRR and Operation from sources Other than Batteries
The AME8819 is designed to deliver low-dropout voltage and low quiescent currents in battery-powered system. Power-supply rejection ratio is 60dB(Typ.) at 1KHz (see PSRR vs Frequency Curve).When operating from sources other than batteries, PSRR and transient response can be improved by increasing input, output capacitors.
