1.5 A Adjustable and 3.3 V
Fixed Output Linear
Regulator
The NCP1086 linear regulator provides 1.5 A at 3.3 V or adjustable
output voltage. The adjustable output voltage device uses two external
resistors to set the output voltage within a 1.25 V to 5.5 V range.
The regulators is intended for use as post regulator and
microprocessor supply. The fast loop response and low dropout
voltage make this regulator ideal for applications where low voltage
operation and good transient response are important.
The circuit is designed to operate with dropout voltages less than
1.4 V at 1.5 A output current. Device protection includes overcurrent
and thermal shutdown.

3. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output
voltage due to thermal gradients or temperature changes must be taken into account separately.
4. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package.
5. Dropout voltage is a measurement of the minimum input/output differential at full load.
6. The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the
output voltage is selected to meet the minimum requirement.
7. Guaranteed by design, not 100% tested in production.
8. Thermal shutdown is 100% functionally tested in production.

APPLICATIONS INFORMATION
The NCP1086 voltage regulator series provides
overall output voltage. The adjust pin current (typically
adjustable and 3.3 V output voltages at currents up to 1.5 A.
The regulator is protected against overcurrent conditions
and includes thermal shutdown.

should be taken into account if precise adjustment of V
is necessary.
OUT
The NCP1086 series has a composite PNP−NPN output
transistor and requires an output capacitor for stability. A
detailed procedure for selecting this capacitor is included in
the Stability Considerations section.

Adjustable Operation
The adjustable output device has an output voltage range
of 1.25 V to 5.5 V. An external resistor divider sets the
output voltage as shown in Figure 15. The regulator
maintains a fixed 1.25 V (typical) reference between the
output pin and the adjust pin.
A resistor divider network R1 and R2 causes a fixed
current to flow to ground. This current creates a voltage
across R2 that adds to the 1.25 V across R1 and sets the
R1 is chosen so that the minimum load current is at least
2.0 mA. R1 and R2 should be the same type, e.g. metal film
for best tracking over temperature. While not required, a
bypass capacitor from the adjust pin to ground will improve
ripple rejection and transient response. A 0.1 mF tantalum
capacitor is recommended for “first cut” design. Type and
value may be varied to obtain optimum performance vs
price.

considerations in such a design are powerup and short circuit
capability.
Stability Considerations
The output or compensation capacitor helps determine
three main characteristics of a linear regulator: startup delay,
load transient response and loop stability.
In most applications, ramp−up of the power supply to V
IN
is fairly slow, typically on the order of several tens of
milliseconds, while the regulator responds in less than one
microsecond. In this case, the linear regulator begins
The capacitor value and type is based on cost, availability,
size and temperature constraints. A tantalum or aluminum
electrolytic capacitor is best, since a film or ceramic
capacitor with almost zero ESR can cause instability. The
aluminum electrolytic capacitor is the least expensive
solution. However, when the circuit operates at low
temperatures, both the value and ESR of the capacitor will
vary considerably. The capacitor manufacturers’ data sheet
provides this information.

large enough that the pass transistor conducts current. The
load at this point is essentially at ground, and the supply
voltage is on the order of several hundred mV, with the result
that the pass transistor is in dropout. As the supply to V
IN
increases, the pass transistor will remain in dropout, and
current is passed to the load until V
reaches the point at
A 22 mF tantalum capacitor will work for most
applications, but with high current regulators such as the
NCP1086 series the transient response and stability improve
with higher values of capacitance. The majority of
applications for this regulator involve large changes in load
current, so the output capacitor must supply the
instantaneous load current. The ESR of the output capacitor
causes an immediate drop in output voltage given by:
OUT
which the IC is in regulation. Further increase in the supply
voltage brings the pass transistor out of dropout. The result
is that the output voltage follows the power supply ramp−up,
staying in dropout until the regulation point is reached. In
this manner, any output voltage may be regulated. There is
no theoretical limit to the regulated voltage as long as the
V
IN
to V
differential of 7.0 V is not exceeded.
OUT
However, the possibility of destroying the IC in a short
DV + DI ESR
circuit condition is very real for this type of design. Short
circuit conditions will result in the immediate operation of
the pass transistor outside of its safe operating area.
Overvoltage stresses will then cause destruction of the pass
transistor before overcurrent or thermal shutdown circuitry
can become active. Additional circuitry may be required to
For microprocessor applications it is customary to use an
output capacitor network consisting of several tantalum and
ceramic capacitors in parallel. This reduces the overall ESR
and reduces the instantaneous output voltage drop under
load transient conditions. The output capacitor network
should be as close as possible to the load for the best results.

fail−safe operation is required. One possible clamp circuit is
illustrated in Figure 16; however, the design of clamp
circuitry must be done on an application by application
basis. Care must be taken to ensure the clamp actually
protects the design. Components used in the clamp design
must be able to withstand the short circuit condition
indefinitely while protecting the IC.

Protection Diodes
When large external capacitors are used with a linear

If the input voltage of the regulator gets shorted, the output

connected as shown in Figure 17 or Figure 18 is
recommended.

Calculating Power Dissipation and
Heatsink Requirements
Output Voltage Sensing
The NCP1086 linear regulator includes thermal shutdown
and current limit circuitry to protect the device. High power
regulators such as these usually operate at high junction
temperatures so it is important to calculate the power
dissipation and junction temperatures accurately to ensure
that an adequate heatsink is used.
Since the NCP1086 is a three terminal regulator, it is not
possible to provide true remote load sensing. Load
regulation is limited by the resistance of the conductors
connecting the regulator to the load.
For best results the fixed output regulator should be
connected as shown in Figure 19.
