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 inversely proportional to the size of the BYP capacitor. Applications requiring a slow rampup 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. Bench testing is the best method for determining the proper type and value of the capacitor since the high frequency characteristics of electrolytic capacitors vary widely, depending on type and manufacturer. A high quality 2.2F aluminum electrolytic capacitor works in most application circuits, but the same stability often can be obtained with a 1F tantalum electrolytic. Figure 1 represents a SPX3819 standard application 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 minimum value of output capacitance is a function of 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 k and for best results, R2 should be between 22 k and 47k. Typical Applications Circuits A 10nF capacitor on the BYP pin will significantly reduce output noise, but it may be left unconnected if the output noise is not a major VIN 1 VOUT 5 VIN 1 + + SPX3819 + 4 + SPX3819 SOT-23 GND 3 3 EN 4 EN BYP (Opt.)

Solved by SPX3819: FAQ TM Part Number: SPX3819 Date: Sept14-06 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 12V input? Answer: The SPX3819 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 SPX3819: 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. SIPEX FAQ (c) 2006 Sipex Corporation For further assistance, contact Sipex Technical Support: Sipexsupport@sipex.com 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 0.01uF 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 10nF 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 1 AMP per 25S 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.

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.

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.

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.

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 70C of operation at 60% and 90% confidence levels have been calculated and listed below.

All units passed. Early Life Failure Rate Testing Early Life Test - 600 units were subject to Early Life test for 48 Hours. All units passed Additional Reliability Tests 77 of the units were placed on Unbiased HAST testing, 77 of the units were placed on Thermal Shock testing, and 77 on -65C/+150C Temperature Cycle testing.
