FAN1582
3A Adjustable/Fixed Ultra Low Dropout
Linear Regulator
Description
Features
The FAN1582, FAN1582-1.5, and FAN1582-2.5 are ultra-low
dropout regulators with 3A output current capability. These
devices have been optimized for low voltage applications
including VTT bus termination, where transient response and
minimum input voltage are critical. The FAN1582 is ideal
for low voltage microprocessor applications requiring a reg-
ulated output from 1.3V to 5.7V with a power input supply
of 1.75V to 6.5V. The FAN1582-1.5 offers fixed 1.5V with
3A current capabilities for GTL+ bus VTT termination. The
FAN1582-2.5 offers fixed 2.5V with 3A current capability
for logic IC operation and processors while minimizing the
overall power dissipation.

measured at a constant junction temperature by low duty cycle pulse testing.

input/output differential and the output current. Guaranteed maximum output power will not be available over the full input/

until both supplies are operating. If the control voltage
comes up first, the output current will be typically limited to
about 3.0 mA until the power input voltage comes up. If the
power input voltage comes up first the output will not turn on
at all until the control voltage comes up. The output can
never come up unregulated.
General
The FAN1582, FAN1582-1.5, and FAN1582-2.5 are three-
terminal regulators optimized for GTL+ VTT termination and
logic applications. These devices are short-circuit protected,
and offer thermal shutdown to turn off the regulator when the
junction temperature exceeds about 150°C. The FAN1582
series provides low dropout voltage and fast transient
response. Frequency compensation uses capacitors with low
ESR while still maintaining stability. This is critical in
addressing the needs of low voltage high speed microproces-
sor buses like GTL+.
The FAN1582 can also be used as a single supply device
with the control and power inputs tied together. In this mode,
the dropout is determined by the minimum control voltage.

Functions

The FAN1582 series requires an output capacitor as a part of
the frequency compensation. It is recommended to use a 22µF
solid tantalum or a 100µF aluminum electrolytic on the output
to ensure stability. The frequency compensation of these
devices optimizes the frequency response with low ESR capaci-
tors. In general, it is suggested to use capacitors with an ESR
of <0.3Ω. It is also recommended to use bypass capacitors
such as a 22µF tantalum or a 100µF aluminum on the adjust
The FAN1582 utilizes a dual supply approach to maximize
efficiency. The collector of the power device is brought out
to the VIN pin to minimize internal power dissipation under
high current loads. VCNTL provides power for the control
circuitry and the drive for the output NPN transistor. VCNTL
should be at least 1.2 V higher than the output voltage.
Special care was taken to ensure there are no supply-

pin of the FAN1582 for low ripple and fast transient response.
When these bypassing capacitors are not used at the adjust pin,
smaller values of output capacitors provide equally good results.
Ripple Rejection
In applications that require improved ripple rejection, a bypass
capacitor from the adjust pin of the FAN1582 to ground
reduces the output ripple by the ratio of VOUT/1.25V. The
impedance of the adjust pin capacitor at the ripple frequency
should be less than the value of R1 (typically in the range of
100Ω to 120Ω) in the feedback divider network in Figure 1.
Therefore, the value of the required adjust pin capacitor is a
function of the input ripple frequency. For example, if R1 equals
100Ω and the ripple frequency equals 120Hz, the adjust pin
capacitor should be 22µF. At 10kHz, only 0.22µF is needed.
Protection Diodes
In normal operation, the FAN1582 series does not require any
protection diodes. For the FAN1582, internal resistors limit
internal current paths on the adjust pin. Therefore, even with
bypass capacitors on the adjust pin, no protection diode is
needed to ensure device safety under short-circuit conditions.
A protection diode between the input and output pins is usu-
ally not needed. An internal diode between the input and the
output pins on the FAN1582 series can handle microsecond
surge currents of 50A to 100A. Even with large value output
capacitors it is difficult to obtain those values of surge cur-
rents in normal operation. Only with large values of output
capacitance, such as 1000µF to 5000µF, and with the input
pin instantaneously shorted to ground can damage occur. A
crowbar circuit at the input can generate those levels of current;
a diode from output to input is then recommended, as shown
in Figure 1. Usually, normal power supply cycling or system
“hot plugging and unplugging” will not generate current
large enough to do any damage.
Output Voltage
The FAN1582 regulator develops a 1.25V reference voltage
between the output pin and the adjust pin (see Figure 2).
Placing a resistor R1 between these two terminals causes a
constant current to flow through R1 and down through R2 to
set the overall output voltage. Normally, this current is the
specified minimum load current of 10mA.
The current out of the adjust pin adds to the current from R1
and is typically 50µA. Its output voltage contribution is small
and only needs consideration when a very precise output
voltage setting is required.
The adjust pin can be driven on a transient basis 7V with
respect to the output, without any device degradation. As with
any IC regulator, exceeding the maximum input-to-output
voltage differential causes the internal transistors to break
down and none of the protection circuitry is then functional.

The FAN1582 family provides true remote sensing, eliminat-
ing output voltage errors due to trace resistance. To utilize
remote sensing, connect the VSENSE pin directly to the
load, rather than at the VOUT pin. If the load is more than 1"
away from the FAN1582, it may be necessary to increase the
load capacitance to ensure stability.

Thermal Considerations
The FAN1582 series protect themselves under overload con-
ditions with internal power and thermal limiting circuitry.
However, for normal continuous load conditions, do not exceed
maximum junction temperature ratings. It is important to
consider all sources of thermal resistance from junction-to-
ambient. These sources include the junction-to-case resistance,
the case-to-heat sink interface resistance, and the heat sink
resistance. Thermal resistance specifications have been
developed to more accurately reflect device temperature and
ensure safe operating temperatures. The electrical character-

istics section provides a separate thermal resistance and
maximum junction temperature for both the control circuitry
and the power transistor. Calculate the maximum junction
temperature for both sections to ensure that both thermal
limits are met.
The power dissipation in this application is:
PD = (VIN - VOUT) * (IOUT) = (3.6-1.47) * (3) = 6.39W
From the specification table,
For example, look at using an FAN1582M-1.5 to generate
3A @ 1.5V 2% from a 3.3V source (3.2V to 3.6V).
TJ = TA + (PD) * (Θ Case-to-Ambient + ΘJC)
= 70 + (6.39) * (5 + 3) = 121°C
Assumptions:
The junction temperature is below the maximum rating.
• Vin = 3.6V worst case
• VOUT = 1.47V worst case
• IOUT = 3A continuous
Junction-to-case thermal resistance is specified from the IC
junction to the bottom of the case directly below the die. This
is the lowest resistance path for heat flow. Proper mounting
ensures the best thermal flow from this area of the package to
the heat sink. Use of a thermally conductive material at the
case-to-heat sink interface is recommended. Use a thermally
conductive spacer if the case of the device must be electri-
cally isolated and include its contribution to the total thermal
resistance.
• TA = 70°C
• Θ Case-to-Ambient = 5°C/W (assuming both a heatsink and a
thermally conductive material)
