DESCRIPTION
■ Portable/Palm Top/Notebook
Computers
■ Battery Chargers
The SPX2810 is a low power positive-voltage regulator designed to satisfy moderate power
requirements with a cost effective, small footprint solution. This device is an excellent choice for
use in battery-powered applications and portable computers. The SPX2810 has a very low
quiescent current and a low dropout voltage of 1.1V at full load. As output current decreases,
quiescent current flows into the load, increasing efficiency. SPX2810 is available in adjustable
or fixed 2.5V, 3.0V and 3.3V output voltages.
The SPX2810 is offered in several industry standard 3-pin surface mount packages: SOT-223,
TO-252, TO-220 and TO-263. An output capacitor of 10µF or larger, provides unconditionally
stability for most applications.

APPLICATION INFORMATION
Output Capacitor
50 X 50mm
To ensure the stability of the SPX1202, an
output capacitor of at least 10µF (tantalum or
ceramic) or 50µF (aluminum) is required. The
value may change based on the application
requirements of the output load or temperature
range. The value of ESR can vary based on the
type of capacitor used in the applications. The
recommended value for ESR is 0.5Ω or less. A
largervalue ofoutput capacitance (up to100µF)
can improve the load transient response.

16 X 10mm
Figure 7. Substrate Layout for SOT-223 for thermal
experiment.
SOLDERING METHODS
The thermal interaction from other components
in the application can effect the thermal resis-
tance of the SPX2810. The actual thermal resis-
tance can be determined with experimentation.
SPX2810 power dissipation is calculated as
follows:
The SPX2810 SOT-223 package is designed to
be compatible with infrared reflow or vapor-
phase reflow soldering techniques. During sol-
dering, the non-active or mildly active fluxes
may be used. The SPX2810 die is attached to
the heatsink lead which exits opposite the input,
output, and ground pins.
PD = (VIN - VOUT)(IOUT
)
Maximum Junction Temperature range:
Hand soldering and wave soldering should be
avoided since these methods can cause damage
to the device with excessive thermal gradients
on the package. The SOT-223 recommended
soldering method are as follows: vapor phase
reflow and infrared reflow with the component
preheated to within 65°C of the soldering tem-
perature range.
TJ = T
(max) + PD* (Junction to ambient
AMBIENT Thermal Resistance)
Although the SPX2810 offers some limiting
circuitry for overload conditions, it is still nec-
essary to insure that maximum junction
tepmerature is not exceeded. Heat will flow
through the lowest resistance path, in this case
the junction to case. Therfore proper mounting
of the regulator to the board is critical. The case
of the device is electrically connected to the
output. If the case must be electrically isolated,
a thermal nonconductive spacer should be used
between the case and the board. It thermal resis-
tance must be taken into account.
THERMAL CHARACTERISTICS
The thermal resistance of SPX2810 depends on
type of package and PC board layout as shown
in Table 1. The SPX2810 features the internal
thermal limiting to protect the device during
overload conditions. Special care needs to be
taken during continuous load conditions such
that the maximum junction temperature does
not exceed 125°C. Thermal protection is acti-
vated at >144°C and deactiviated at <137°C.
For example:
VIN =10V, VOUT =5V. IOUT =1.5A and TA =50°C/W
ThetaJC=3°C/W, thetaSinkCase= 6°C/W
thetaSink=0.5°C/W
Power dissipation is calculated as
PD= (VIN-VOUT)* IOUT=7.5W
Taking the FR-4 printed circuit board and 1/16
thick with 1 ounce copper foil as an experiment,
the PCB material is effective at transmitting
heat with the tab attached to the pad area and a
ground plane layer on the backside of the sub-
strate. Refer to table 1 for the results of the
experiment.
Junction Temperature will be
TJ=TA + PD*(thetaCase-Hs +thetaHs + thetaJc) or
TJ = 50 + 7.5(0.5+6+3) = 121.25°C

If an ADJ-bypass capacitor is used, the
amplitude of the output ripple will be inde-
pendent of the output voltage. If an ADJ-
bypass capacitor is not used, the output ripple
will be proportional to the ratio of the output
voltage to the reference
Ripple Rejection
Ripple rejection can be improved by adding a
capacitor between the ADJ pin and ground as
shown in Figure 6. When ADJ pin bypassing is
used, the value of the output capacitor required
increases to its maximum. If the ADJ pin is not
bypassed, the value of the output capacitor can
be lowered to 10(F for an electrolytic aluminum
capacitor or 2.2µF for a solid tantalum capacitor
(Fig 10). However the value of the ADJ-bypass
capacitor should be chosen with respectto the
following equation:
voltage:
M = VOUT / VREF
Where M = multiplier for the ripple seen when
the ADJ pin
is optimally bypassed.
C = 1 / ( 6.28 * FR * R1 )
VREF =1.25V
Where C = value of the capacitor in Farads
(select an equal or larger standard value),
F = ripple frequency in Hz,

Output Voltage
The output of the adjustable regulator can be set to any voltage between 1.25V and 10V. The value
of VOUT can be quickly approximated using the formula (Figure 9)
VOUT=1.25 *(R1 + R2)/R1.
A small correction to this formula is required depending on the values of resistors R1 and R2, since
adjustable pin current (approx 50µA) flows through R2. When IADJ is taken into account, the formula
becomes
VOUT = VREF(1+ (R2/R1)) + IADJ * R2, where VREF=1.25V.
Layout Considerations

it is best to connect R1 to the case as illustrated in Figure 11. For the same reason, R2 should be
connected to the negative side of the load.
