The capacitance can vary with DC bias conditions as well as temperature and frequency of operation. Capacitor values will also show some decrease over time due to aging. The capacitor parameters are also dependant on the particular case size, with smaller sizes giving poorer performance figures in general. As an example, Figure 1 shows a typical graph comparing different capacitor case sizes in a Capacitance vs. DC Bias plot. As shown in the graph, increasing the DC Bias condition can result in the capacitance value falling below the minimum value given in the recommended capacitor specifications table (0.7F in this case). Note that the graph shows the capacitance out of spec for the 0402 case size capacitor at higher bias voltages. It is therefore recommended that the capacitor manufacturers' specifications for the nominal value capacitor are consulted for all conditions, as some capacitor sizes (e.g. 0402) may not be suitable in the actual application. Application Hints OPERATION DESCRIPTION The LP5996 is a low quiescent current, power management IC, designed specifically for portable applications requiring minimum board space and smallest components. The LP5996 contains two independently selectable LDOs. The first is capable of sourcing 150mA at outputs between 0.8V and 3.3V. The second can source 300mA at an output voltage of 0.8V to 3.3V. INPUT CAPACITOR An input capacitor is required for stability. It is recommended that a 1.0F capacitor be connected between the LP5996 input pin and ground (this capacitance value may be increased without limit). This capacitor must be located a distance of not more than 1cm from the input pin and returned to a clean analogue ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input. Important: Tantalum capacitors can suffer catastrophic failures due to surge current when connected to a lowimpedance source of power (like a battery or a very large capacitor). If a tantalum capacitor is used at the input, it must be guaranteed by the manufacturer to have a surge current rating sufficient for the application. There are no requirements for the ESR (Equivalent Series Resistance) on the input capacitor, but tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the capacitance will remain approximately 1.0F over the entire operating temperature range. OUTPUT CAPACITOR The LP5996 is designed specifically to work with very small ceramic output capacitors. A 1.0F ceramic capacitor (temperature types Z5U, Y5V or X7R) with ESR between 5m to 500m, is suitable in the LP5996 application circuit. For this device the output capacitor should be connected between the VOUT pin and ground. It is also possible to use tantalum or film capacitors at the device output, COUT (or VOUT), but these are not as attractive for reasons of size and cost (see the section Capacitor Characteristics). The output capacitor must meet the requirement for the minimum value of capacitance and also have an ESR value that is within the range 5m to 500m for stability. 20171540 FIGURE 1. Graph Showing a Typical Variation in Capacitance vs DC Bias The capacitance value of ceramic capacitors varies with temperature. The capacitor type X7R, which operates over a temperature range of -55C to +125C, will only vary the capacitance to within 15%. The capacitor type X5R has a similar tolerance over a reduced temperature range of -55C to +85C. Many large value ceramic capacitors, larger than 1F are manufactured with Z5U or Y5V temperature characteristics. Their capacitance can drop by more than 50% as the temperature varies from 25C to 85C. Therefore X7R is recommended over Z5U and Y5V in applications where the ambient temperature will change significantly above or below 25C. Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more expensive when comparing equivalent capacitance and voltage ratings in the 0.47F to 4.7F range. Another important consideration is that tantalum capacitors have higher ESR values than equivalent size ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic capacitor with the same ESR value. It should also be noted that the ESR of a typical tantalum will NO-LOAD STABILITY The LP5996 will remain stable and in regulation with no external load. This is an important consideration in some circuits, for example CMOS RAM keep-alive applications. CAPACITOR CHARACTERISTICS The LP5996 is designed to work with ceramic capacitors on the output to take advantage of the benefits they offer. For capacitance values in the range of 0.47F to 4.7F, ceramic capacitors are the smallest, least expensive and have the lowest ESR values, thus making them best for eliminating high frequency noise. The ESR of a typical 1.0F ceramic capacitor is in the range of 20m to 40m, which easily meets the ESR requirement for stability for the LP5996. For both input and output capacitors, careful interpretation of the capacitor specification is required to ensure correct device operation. The capacitor value can change greatly, depending on the operating conditions and capacitor type. www.national.com 10 filter which reduces the noise level on both outputs of the device. There is also some improvement in PSSR and line transient performance. Internal circuitry ensures rapid charging of the CBYP capacitor during start-up. A 10nF, high quality ceramic capacitor with either NPO or COG dielectric is recommended due to their low leakage characteristics and low noise performance. ENABLE CONTROL The LP5996 features active high enable pins for each regulator, EN1 and EN2, which turns the corresponding LDO off when pulled low. The device outputs are enabled when the enable pins are set to high. When not enabled the regulator output is off and the device typically consumes 2nA. If the application does not require the Enable switching feature, one or both enable pins should be tied to VIN to keep the regulator output permanently on. To ensure proper operation, the signal source used to drive the enable inputs must be able to swing above and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section under VIL and VIH. SAFE AREA OF OPERATION Due consideration should be given to operating conditions to avoid excessive thermal dissipation of the LP5996 or triggering its thermal shutdown circuit. When both outputs are enabled, the total power dissipation will be PD(LDO1) + PD(LDO2) where PD = (VIN - VOUT) x IOUT for each LDO In general, device options which have a large difference in output voltage will dissipate more power with both outputs enabled, due to the input voltage required for the higher output voltage LDO. In such cases, especially at elevated ambient temperature, it may not be possible to operate both outputs at maximum current at the same time. BYPASS CAPACITOR The internal voltage reference circuit of the LP5996 is connected to the CBYP pin via a high value internal resistor. An external capacitor, connected to this pin, forms a low-pass 11 www.national.com LP5996 increase about 2:1 as the temperature goes from 25C down to -40C, so some guard band must be allowed.
