THEORY OF OPERATION
Minumum Load
(Larger resistor)
The LX8584/84A/84B series ICs are easy to use Low-Dropout
(LDO) voltage regulators. They have all of the standard self-
protection features expected of a voltage regulator: short circuit
protection, safe operating area protection and automatic thermal
shutdown if the device temperature rises above approximately
165°C.

Stability
The output capacitor is part of the regulator’s frequency
compensation system. Many types of capacitors are available, with
different capacitance value tolerances, capacitance temperature
coefficients, and equivalent series impedances. For all operating
conditions, connection of a 220μF aluminum electrolytic capacitor
or a 47μF solid tantalum capacitor between the output terminal
and ground will guarantee stable operation.
If a bypass capacitor is connected between the output voltage
adjust (ADJ) pin and ground, ripple rejection will be improved
(please see the section entitled “RIPPLE REJECTION”). When
ADJ pin bypassing is used, the required output capacitor value
increases. Output capacitor values of 220μF (aluminum) or 47μF
(tantalum) provide for all cases of bypassing the ADJ pin. If an
ADJ pin bypass capacitor is not used, smaller output citor
values are adequate. The table below shows rmmended
minimum capacitance values for stable operation.
r some ctions, a correctly operating SOA circuit may
power pply system from returning to regulated
er removal of an intermittent short circuit at the
regulator. This is a normal mode of operation which
n most similar products, including older devices such
eries regulators. It is most likely to occur when the
power system input voltage is relatively high and the load
impedance is relatively low.
When the power system is started “cold”, both the input and
output voltages are very close to zero. The output voltage closely
follows the rising input voltage, and the input-to-output voltage
difference is small. The SOA circuit therefore permits the
regulator to supply large amounts of current as needed to develop
the designed voltage level at the regulator output. Now consider
the case where the regulator is supplying regulated voltage to a
resistive load under steady state conditions. A moderate input-to-
output voltage appears across the regulator but the voltage
difference is small enough that the SOA circuitry allows
sufficient current to flow through the regulator to develop the
designed output voltage across the load resistance. If the output
resistor is short-circuited to ground, the input-to-output voltage
difference across the regulator suddenly becomes larger by the
amount of voltage that had appeared across the load resistor. The
SOA circuit reads the increased input-to output voltage, and cuts
back the amount of current that it will permit the regulator to
supply to its output terminal. When the short circuit across the
output resistor is removed, all the regulator output current will
again flow through the output resistor. The maximum current that
the regulator can supply to the resistor will be limited by the SOA
circuit, based on the large input-to-output voltage across the
regulator at the time the short circuit is removed from the output.

If this limited current is not sufficient to develop the designed
voltage across the output resistor, the voltage will stabilize at some
lower value, and will never reach the designed value. Under these
circumstances, it may be necessary to cycle the input voltage
down to zero in order to make the regulator output voltage return
to regulation.

Ripple rejection can be improved by connecting a capacitor
between the ADJ pin and ground. The value of the capacitor
should be chosen so that the impedance of the capacitor is equal in
magnitude to the resistance of R1 at the ripple frequency. The
capacitor value can be determined by using this equation:

APPLICATION NOTE
LOAD REGULATION (continued)
can be used, as long as its added contribution to thermal
resistance is considered. Note that the case of all devices in this
series is electrically connected to the output.
Examples
Even when the circuit is optimally configured, parasitic
resistance can be a significant source of error. A 100 mil (2.54
mm) wide PC trace built from 1 oz. copper-clad circuit board
material has a parasitic resistance of about 5 milliohms per inch of
its length at room temperature. If a 3-terminal regulator used to
supply 2.50 volts is connected by 2 inches of this trace to a load
which draws 5 amps of current, a 50 millivolt drop will appear
between the regulator and the load. Even when the regulator
output voltage is precisely 2.50 volts, the load will only see 2.45
volts, which is a 2% error. It is important to keep the connection
between the regulator output pin and the load as short as possible,
and to use wide traces or heavy-gauge wire.
The minimum specified output capacitance for the regulator
should be located near the regulator package. If several capacitors
are used in parallel to construct the power system output
capacitance, any capacitors beyond the minimum needed to meet
the specified requirements of the regulator should be located near
the sections of the load that require rapidly-changing amounts of
current. Placing capacitors near the sources of load transients will
help ensure that power system transient response is not impaired
by the effects of trace impedance.

Junction-to-case thermal resistance is specified from the IC
junction to the back surface of the case directly opposite the die.
This is the lowest resistance path for heat flow. Proper mounting is
required to ensure the best possible thermal flow from this area of
the package to the heat sink. Thermal compound at the case-to
heat- sink interface is strongly recommended. If the case of the
device must be electrically isolated, a thermally conductive spacer
Next, select a suitable heat sink. The selected heat sink must
have RΘSA < 3.1°C/W. Thermalloy heatsink 6296B has RΘSA
3.0°C/W with 300ft/min air flow.

Finally, verify that junction temperature remains within
specification using the selected heat sink:
TJ = 11W(2.7°C/W +1.0°C/W + 3.0°C/W) + 50°C = 124°C
** Although the device can operate up to150°C junction, it is
recommended for long term reliability to keep the junction
temperature below 125°C whenever possible.
