A.08 7 AME AME8839 n Detailed Description The AME8839 is low-dropout, high PSRR, Low noise linear regulator designed primarily for low noise applications. It is available with present output voltage ranging from 1.2V to 4.5V, and can supply loads up to 300mA. High PSRR, Ultra Low Noise, 300mA CMOS Linear Regulator 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 regulator are optimized for ceramic capacitors. Tantalum Shutdown Mode The AME8839 has enable-control-pin. Drive EN low to shutdown OUT. Drive EN to shutdown the entire chip, reducing supply current to 1µA. Connected EN to logichigh or IN for normal operation. capacitors are not recommended. Bypass capacitor can be in between 0.1µF~0.01µF. A larger capacitor improves AC ripple rejection and reduce noise, but also make the output come up slowly. PSRR and Operation from sources Other than Bat- Circuit Limit The AME8839 contains current limiters which monitor and control the pass transistor's Gate voltage, limiting the guaranteed maximum output current to 450mA minimum. The output can be shorted to ground for an indefinite time without damaging the part. teries The AME8839 is designed to deliver low-dropout voltage, low noise and high PSRR in low noise applications. Power-supply rejection ratio is 70dB (Typ.) at 10KHz. When operating from sources other than betteries, PSRR and transient response can be improved by increasing Thermal-Overload Protection input, output and bypass capacitors (see PRSS vs Frequency Curve). Thermal-overload protection limits total power dissipation in the AME8839. When the junction temperaturee arrive TJ = 150oC approximately, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool. Capacitor Selection and Regulator Stability Use a 1µF capacitor on the AME8839 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. 8 Rev.
