Power is supplied to the device through this pin and requires an input filter capacitor. In general, an

input capacitor in the range of 1µF to 10µF is sufficient.

The output supplies power to loads. The output capacitor is required to provide a stable output voltage.

The APE8800-3 is stable with an output capacitor of 1µF or greater. A larger output capacitor will

be required for applications with large transient loads to limit peak voltage transients, and can also

reduce output noise, improve stability and PSRR.

Application Description

The APE8800-3 series are low dropout linear regulators that can provide 300mA output current with a drop-out voltage of about 2-300mV. Also, current limit and on-chip thermal shutdown features provide protection against any combination of overload or junction temperature that exceeds the shutdown temperature.

1.Output and Input Capacitor

The APE8800-3 regulator is designed to be stable with a wide range of output capacitors. The ESR of the output capacitor affects stability. Larger values of the output capacitor decrease the peak deviations and provide improved transient response for larger current changes.

The various capacitor types (aluminum, ceramic, tantalum) have different characteristics such as

temperature and voltage coefficients. All ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior across temperature and applications. Common dielectrics used are X5R, X7R and Y5V. It is recommended

to use 1uF to 10uF X5R or X7R dielectric ceramic capacitors with 30mΩ to 50mΩ ESR range betw-

een device outputs to ground for transient stability. The APE8800-3 is designed to be stable with low ESR ceramic capacitors, and higher values of capacitors and ESR can improve output stability.

APE8800-3

So the ESR of the output capacitor is very important because it generates a zero to provide phase lead for loop stability.

There are no requirements for the ESR on the input capacitor, but its voltage and temperature coefficient have to be considered for the device application environment.

2.Protection Features In order to prevent overloading or a thermal

condition from damaging the device, the APE88 regulator has internal thermal and current-limiting functions designed to protect the device. It

will rapidly shut off the internal P-channel MOSFET pass element during overloading or an over-temperature condition.

3.Thermal Consideration The power handling capability of the device is

limited by the maximum operation junction

temperature (125°C). The power dissipated by the device can be estimated by PD = IOUT ×

(VIN-VOUT). This power dissipation must be lower than the maximum power dissipation listed in the “Absolute Maximum Ratings” section.
