®
The SPX1117 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 SPX1117 features very low
quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases,
quiescent current flows into the load, increasing efficiency. SPX1117 is available in adjustable
or fixed 1.5V, 1.8V, 2.5V,2.5V, 2.85V, 3.0V, 3.3V and 5V output voltages.
The SPX1117 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220
and TO-263. An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF
capacitor is sufficient for most applications.

Output Capacitor
To ensure the stability of the SPX1117, an
output capacitor of at least 2.2µF (tantalum or
ceramic) or 10µF (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 to
guarantee stability. The recommended value
for ESR is 0.5 or less. A larger value of
output capacitance (up to 100µF) can improve
the load transient response.
Soldering Methods
The SPX1117 SOT-223 package is designed
to be compatible with infrared reflow or
vapor-phase reflow soldering techniques.
During soldering, the non-active or mildly
active fluxes may be used. The SPX1117 die
is attached to the heatsink lead which exits
opposite the input, output, and ground pins.
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 temperature range.

Thermal Characteristics
The thermal resistance of SPX1117 (SOT-223
Package) is 15°C/W from junction to tab and 31
°C/W from tab to ambient for a total of 46 °C/W
from junction to ambient (Table 1). The SPX1117
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 tem-
perature does not exceed 125 °C. Thermal pro-
tection is activated at >155°C and deactiviated
at <140 °C.
Taking the FR-4 printed circuit board and 1/16
thick with 1 ounce copper foil as an experiment
(fig.13), the PCB material is effective at trans-
mitting heat with the tab attached to the pad area
and a ground plane layer on the backside of the
substrate. Refer to table 1 for the results of the
experiment.
The thermal interaction from other components
in the application can effect the thermal resis-
tance of the SPX1117. The actual thermal
resistance can be determined with experimenta-
tion.
SPX1117 power dissipation is calculated as
follows:
PD = (VIN - VOUT)(IOUT)
Maximum Junction Temperature range:
TJ = TA(max) + PD* thermal resistance
(junction-to-ambient)
Maximum junction temperature must not ex-
ceed the 125°C.
Ripple Rejection
Ripple rejection can be improved by adding a
capacitor between the ADJ pin and ground as
shown in Figure 23. When ADJ pin bypassing
is used, the value of the output capacitor re-
quired increases to its maximum. If the ADJ pin
is not bypassed, the value of the output capacitor
can be lowered to 10µF for an electrolytic alu-
minum capacitor or 2.2µF for a ceramic or solid
tantalum capacitor (Fig 22).
However the value of the ADJ-bypass capacitor
should be chosen with respect to the following
equation:
C = 1 / ( 6.28 * FR * R1 )
Where
C = value of the capacitor in Farads
(select an equal or larger standard value),
FR = ripple frequency in Hz,
R1 = value of resistor R1 in Ohms.
If an ADJ-bypass capacitor is used, the ampli-
tude of the output ripple will be independent 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
voltage:
M = VOUT / VREF
Where M = multiplier for the ripple seen when
the ADJ pin is optimally bypassed.
VREF =1.25V
Ripple rejection for the adjustable version is
shown in Figure 20.

Output Voltage
The output of the adjustable regulator can be set
to any voltage between 1.25V and 15V. The
value of VOUT can be quickly approximated using
the formula
VOUT=1.25 *(R1 + R2)/R1.
A small correction to this formula is required
depending on the values of resistors R1 and R2,
since the adjustable pin current (approx 50µA)
flows through R2. When IADJ is taken into ac-
count, the formula becomes

VOUT = VREF(1+ (R2/R1)) + IADJ * R2,
where
VREF=1.25V.
Layout Considerations
Parasitic line resistance can degrade load regu-
lation. In order to avoid this, connect R1 directly
to VOUT as illustrated in Figure 25. For the same
reason, R2 should be connected to the negative
side of the load.
