TYPICAL APPLICATION

PACKAGE/ORDERING INFORMATION

APE8840 is dual low dropout positive regulator with

minimum of 600mA output current capability. The product is

specifically designed to provide well-regulated supply for lo

voltage IC applications such as high-speed bus termination

and low current 3.3V/1.8V, logic supply. APE8840 series are

guaranteed to have <1.5V dropout at full load current

making it ideal to provide well regulated outputs dual

channels with up to 12V input supply, but depend on Powe

Dissipation Limitation for using. To prevent oscillation, it is

recommended to use minimum 1uF dielectric capacitors fo

Input/Output Capacitors, In general, the input capacitor in

the range of 1uF to 10uF sufficient.

Note1: See thermal regulation specifications for changes in output voltage due to heating effects.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing.

Load regulation is measured at the output lead = 1/18” from the package.

Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 2W. Power dissipation is

determined by the input/output differentially and the output current. Guaranteed maximum power dissipation

will not be available over the full input/output range.

Note3: Quiescent current is defined as the minimum output current that requires maintaining regulation. At 12V

input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.

PIN DESCRIPTIONS

PIN SYMBOL PIN DESCRIPTION

GND Ground for fix output version

The output of the regulator. A minimum of 1uF capacitor (10mΩ < ESR < 1Ω)

must be connected from this pin to ground to insure stability.

The input pin of regulator. Typically a minimum of 1uF capacitor is connected

from this pin to ground to insure that the input voltage does not sag below the

minimum dropout voltage during the load transient response. The pin must

always be 1.5V higher than Vout in order for the device to regulate properly.
