(Top View)
AP1086 is a low dropout positive adjustable or fixed-mode
regulator with 1.5A output current capability. The product is
specifically designed to provide well-regulated supply for low
voltage IC applications such as high-speed bus termination
and low current 3.3V logic supply. AP1086 is also well suited
for other applications such as VGA cards. AP1086 is
guaranteed to have lower than 1.4V dropout at full load
current making it ideal to provide well-regulated outputs of
1.25V to 5.0V with 4.7 to 12V input supply by different output
voltage.

Notes: 2. 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.
3. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference in input and
output and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
4. Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is
guaranteed to regulate if the output current is greater than 10mA.

1.5A LOW DROPOUT POSITIVE ADJUSTABLE OR
FIXED-MODE REGULATOR
Functional Description
Introduction
The AP1086 adjustable or fixed-mode Low Dropout (LDO) regulator is a 3 terminal device which can easily be
programmed by internal mask change to any voltages within the range of 1.25V to VIN-1.4V. The AP1086 only
needs 1.4V differential between VIN and VOUT to maintain output regulation. In addition, the output voltage
tolerances are also extremely tight and they include the transient response as part of the specification. For
example, Intel VRE specification calls for a total of +/- 100mV including initial tolerance, load regulation and 0 to
1.5A load step.
The AP1086 is specifically designed to meet the fast current transient needs as well as providing an accurate
initial voltage, reducing the overall system cost with the need for fewer output capacitors.
Load Regulation
Since the AP1086 is only a 3 terminal device, it is not possible to provide true remote sensing of the output
voltage at the load. But it can supply good load regulation by internal feedback bypass the external loss such as
adjustable mode.
Stability
The AP1086 requires the use of an output capacitor as part of the frequency compensation in order to make the
regulator stable. For most applications a minimum of 10uF aluminum electrolytic capacitor insures both stability
and good transient response.
Thermal Design
The AP1086 incorporates an internal thermal shutdown that protects the device when the junction temperature
exceeds the maximum allowable junction temperature. Although this device can operate with junction
temperatures in the range of 150oC, it is recommended that the selected heat sink be chosen such that during
maximum continuous load operation the junction temperature is kept below the temperature.
Layout Consideration
The output capacitors must be located as close to the VOUT terminal of the device as possible. It is recommended
to use a section of a layer of the PC board as a plane to connect the VOUT pin to the output capacitors to prevent
any high frequency oscillation that may result due to excessive trace inductance.
