APE8861 is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for

application with large transit load to limit peak voltage transits, besides could reduce output noise, improve

stability, PSRR.

PIN DESCRIPTION

Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input

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

The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The

Application Information

The APE8861 series are low dropout linear

regulators that could provide 300mA output current

at dropout voltage about 300mV. Besides, current

limit and on chip thermal shutdown features provide

protection against any combination of overload or

ambient temperature that could exceed junction

temperature.

1.Output and Input Capacitor

The APE8861 regulator is designed to be stable

with a wide range of output capacitors. The ESR of

the output capacitor affects stability. Larger value

of the output capacitor decreases the peak

deviations and provides to improve transition

response for larger current changes.

The capacitor types (aluminum, ceramic, and tant-

alum) have different characterizations 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 X5R or X7R dielectric ceramic

capacitors with 30mΩ to 50mΩ ESR range betw-

een device outputs to ground for transient stability.

The APE8861 is designed to be stable with low

ESR ceramic capacitors and higher values of

capacitors and ESR could improve output stability.

So the ESR of 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 device

application environment.

2.Protection Features

In order to prevent overloading or thermal cond-

ition from damaging the device, APE8861

regulator has internal thermal and current

limiting functions designed to protect the device.

It will rapidly shut off PMOS pass element

during overloading or over temperature

condition.

3.Thermal Consideration

The power handling capability of the device will

be limited by maximum operation junction temp-

erature (125°C). The power dissipated by the

device will be estimated by PD = IOUT ×

(VIN-VOUT). The power dissipation should be

lower than the maximum power dissipation

listed in “Absolute Maximum Ratings” section.
