DESCRIPTION
The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In
addition, this device offers a very low ground current of 800µA at 100mA output. The SPX3819 has
an initial tolerance of less than 1% max and a logic compatible ON/OFF switched input. When
disabled, power consumption drops to nearly zero. Other key features include reverse battery
protection, current limit, and thermal shutdown. The SPX3819 includes a reference bypass pin for
optimal low noise output performance. With its very low output temperature coefficient, this device
also makes a superior low power voltage reference.
The SPX3819 is an excellent choice for use in battery-powered applications such as cordless
telephones, radio control systems, and portable computers. It is available in several fixed voltages
-- 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 5.0V -- or with an adjustable output. This device is offered
in 8 pin NSOIC, 8 pin DFN and 5-pin SOT-23 packages.

NOTES
Note 1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ(max) the junction to ambient thermal
resistance, and the ambient θJA, and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is
given: PD(max) = (TJ(max)-TA)/θJA, exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will
go into thermal shutdown. The θJA of the SPX3819 is 220°C/W mounted on a PC board.
Note 2: Not applicable to output voltage 2V or less.

APPLICATION INFORMATION
The SPX3819 requires an output capacitor for
device stability. Its value depends upon the
application circuit. In general, linear regulator
stability decreases with higher output currents.
In applications where the SPX3819 is sourcing
less current, a lower output capacitance may be
sufficient. For example, a regulator outputting
only 10mA, requires approximately half the
capacitance as the same regulator sourcing
150mA.
concern. The SPX3819 start-up speed is in-
versely proportional to the size of the BYP
capacitor. Applications requiring a slow ramp-
up of the output voltage should use a larger
CBYP. However, if a rapid turn-on is necessary,
the BYP capacitor can be omitted.
The SPX3819’s internal reference is available
through the BYP pin.
Benchtestingisthebestmethodfordetermining
the proper type and value of the capacitor since
the high frequency characteristics of electro-
lytic capacitors vary widely, depending on type
and manufacturer. A high quality 2.2µF alumi-
num electrolytic capacitor works in most appli-
cation circuits, but the same stability often can
be obtained with a 1µF tantalum electrolytic.
Figure 1 represents a SPX3819 standard appli-
cation circuit. The EN (enable) pin is pulled
high (>2.0V) to enable the regulator.
To disable the regulator, EN < 0.4V.
The SPX3819 in Figure 2 illustrates a typical
adjustable output voltage configuration. Two
resistors (R1 and R2) set the output voltage. The
output voltage is calculated using the formula:
With the SPX3819 adjustable version, the mini-
mumvalueofoutputcapacitanceisafunctionof
the output voltage. The value decreases with
higher output voltages, since closed loop gain is
increased.
VOUT = 1.235V x [ 1 + R1/R2]
R2 must be > 10 kΩꢀand for best results, R2
shouldbebetween22kΩ and47kΩ.
Typical Applications Circuits
A 10nF capacitor on the BYP pin will signifi-
cantly reduce output noise, but it may be left
unconnected if the output noise is not a major

Solved by
SPX3819: FAQ
TM
Part Number: SPX38ꢀ9
Date: Septꢀ4-06
Question:
Assuming a nominal load of 250mA @ 3V DC, how much ground current will be consumed? With a 6V input, will
the part even get warm? How about with a ꢀ2V input?
Answer:
The SPX38ꢀ9 data sheet contains a graph of ground current vs load current for your review.
Also we suggest that you download the Thermal Considerations application note which includes a few example
calculations from the SPX38ꢀ9:
http://www.sipex.com/files/ApplicationNotes/LDOThermal.pdf
The Linear Regulator Heat Calculator could also prove helpful:
http://www.sipex.com/files/ApplicationNotes/ThermalCalculator.xls
Customer bench testing is strongly recommended using intended application circuit to ensure proper operation.
Question:
Is this part similar to your SP6203 CMOS part in the above regard? Or, is it like a conventional regulator (LM7805)
where the excess voltage turns into heat?
Answer:
All LDO’s will transfer most of its energy to heat. To minimize this temperature rise keep the input to output voltage
difference slightly above dropout voltage. See the applications note mentioned above.
Question:
Can ceramic capacitors be used on the output?
Answer:
Ceramic capacitors may be used for this part. For Tantalum or Aluminum Electrolytic types, keep the Equivalent
Series Resistance (ESR) as small as possible.
Question:
Considering the PSRR is 70db, what is a better strategy for filtering the 60Hz ripple from the wall cube? A big high
voltage electrolytic on the input or a smaller, low voltage ceramic on the output? Or, a combination of both?
Answer:
A small common mode choke would be best for filtering this ripple. Variations / combinations of input capacitance
might also help but bench testing would be required.

Question:
Is there any practical limit to how much capacitance is used on the input or output?
Answer:
Input and output capacitance may be increased without limit.
Question:
It would appear, from the data sheet, increasing the Bypass capacitor above 0.0ꢀuF has little improvement in
terms of noise. We use a special low ESL/ESR 0.1uF ceramic as standard for RF bypassing. Any concerns
about using these on your Bypass pin as well?
Answer:
If the bypass pin is to be used a ꢀ0nF ceramic capacitor is suggested. You may also use the value / type
mentioned. The only concern with the bypass feature is that startup time is increased. If startup time is a
concern then the bypass pin should be kept open. Different values of bypass capacitor will result in different
startup times.
Question:
A portion of this application involves modulating a IR LED with a 400KHz signal having a 50% duty cycle or less.
Assumming a drive level of ꢀ AMP per 25µS pulse, will your device even see this as an overload and go into
current limiting? If so, should a large electrolytic be employed on the output?
Answer:
This is a little difficult to answer not knowing how you plan on modulating the LED. If the enable input is used for
modulation it is possible that the device may not react fast enough to provide an output. This is very much true
if the Bypass pin is used. If the output load exceeds the current limit trip point then the output will be turned off
to protect the device. However. if the output is always on and modulation is done with some external circuitry,
then adding extra capacitance to the output could satisfy the current demand of the LED so as not to cause
current limit activation.
Question:
This part is quite attractive in terms of its Reverse Battery Protection feature. Do you have any other more
current/better alternatives?
Answer:
For a 500mA output current device this is the best Sipex offers for package size and performance. Check our
LDO products page for all of Sipex LDO offerings.

For further assistance, contact Sipex Technical Support:
Question:
If a 3V battery pack was connected to the output, without a “wall wart” connected to the input, would any
current flow back through the device?
Answer:
The datasheet does not state that this device is operable in a pre-biased output condition; therefore, leakage
may occur.
Question:
If the 3V battery pack was connected to the input, what would the output voltage be with a 250mA load?
Answer:
If the input voltage is above dropout voltage then the part will regulate for the entire output current range up
to 500mA.

Characterization Report
Conclusion:
Characterization data over temperature and Vcc range show datasheet
parameters meet the spec. Cpk’s for most parameters are comparable between
Hillview and Silan although many show a strong temperature dependence that
tends to produce lower Cpk’s in this analysis.
The performance of SPX5205 parts fabricated at Silan are comparable to the
current SPX5205 parts built from the Hillview fab.
This characterization report applies to the following SPX5205 family of product

Device Description:
The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout
voltage of 390mV (typical) @ 1.5A. These regulators are specifically designed for low
voltage applications that require a low dropout voltage and a fast transient response. They
are fully fault protected against over-current, reverse battery, and positive and negative
voltage transients. On-chip trimming adjusts the reference voltage to 1% initial accuracy.
Other features in the 5 pin versions include Enable and Error Flag.
The SPX29150/51/52/53 is offered in 3-pin and 5-pin TO-220 & TO-263 packages. For a
3A version, refer to the SPX29300 data sheet.

Life Test
Life testing is conducted to determine if there are any fundamental reliability related
failure mechanism(s) present in the device.
These failure mechanisms can be divided roughly into four groups:
1. Process or die related failures such as oxide defects, metallization defects, and
diffusion defects.
2. Assembly related failures such as chip mount defects, wire bond defects, molding
defects, and trim/form/singulation defects.
3. Design related defects.
4. Miscellaneous, undetermined, or application induced failures.
125C Operating Life Test Results
As part of the Sipex design qualification program, the Product/Reliability Engineering
group subjected 231 parts to 168 hours and 1000 hours of 125° C life stress testing.
168 Hour Timepoint
The 231 parts were subjected to the life test profile and completed the stress with no
failures.
1000 Hour Timepoint
231 parts were reintroduced to life stress testing, completing the 1000 hour HTOL time
point without any failures or significant shifts in process parameters
FIT Rate Calculations
FIT rate (failures in time) is the predicted number of failures per billion device hours.
This predicted value is based upon,
SPX29150 Reliability Report
Page 3 of 4
• The Life Test conditions summarized in the HTOL table (time/temperature, device
quantity, failure quantity).
• The Activation Energy (Ea) for potential failure modes. The weighted Activation
Energy(Ea) of observed failure mechanisms for Sipex products has been determined
to be 0.8eV.
Based on the above criteria SPX29150 product FIT rates for 25°, 55°, and 70°C of
operation at 60% and 90% confidence levels have been calculated and listed below.
