LP5952 SNVS469F–OCTOBER2006–REVISEDDECEMBER2015 www.ti.com 7 Detailed Description 7.1 Overview The LP5952 is a dual-supply-rail linear regulator optimized for powering ultralow-voltage circuits from a single Li- Ion cell or 3 cell NiMH/NiCd batteries. In a typical application, BATT is connected to the battery, and IN can be suppliedbytheoutputoffrontstageDC-DCConverter.INdoesnotexceedBATTatanytime. 7.2 Functional Block Diagram BATT IN VREF + - OUT Thermal, Enable and undervoltage, and EN start-up overcurrent management protection GND 7.3 Feature Description 7.3.1 Dual-RailSupply TheLP5952requirestwodifferentsupplyvoltages: • V ,thepowerinputvoltage,isregulatedtothefixedoutputvoltage. IN • V ,thebiasinputvoltage,suppliesinternalcircuitry. BATT It is important that V does not exceed V at any time. If the device is used in the typical post-regulation IN BATT application as shown in Figure 18, the sequencing of the two power supplies is not an issue because V BATT supplies both the DC-DC regulator and the LP5952 device. The output voltage of the DC-DC regulator takes some time to rise up and supply the input voltage of the device. In this application V always ramps up more IN slowlythanV . BATT IfV isshortedtoV ,thevoltagesatthetwosupplypinsrampupsimultaneouslycausingnoproblems. IN BATT However, in applications with two independent supplies connected to the LP5952, special care must be taken to ensurethatV isalways≤ V . IN BATT 7.3.2 No-LoadStability The LP5952 remains stable and in regulation with no external load. This is an important consideration in some circuits,forexample,CMOSRAMkeep-aliveapplications. 7.3.3 FastTurnon Fast turnon is ensured by an optimized architecture allowing a fast ramp of the output voltage to reach the target voltagewhiletheinrushcurrentiscontrolledlowat120mAtypical(foraC of2.2µF).

LP5952 www.ti.com SNVS469F–OCTOBER2006–REVISEDDECEMBER2015 Feature Description (continued) 7.3.4 Short-CircuitProtection The LP5952 is short-circuit protected and, in the event of a peak overcurrent condition, the output current throughtheNFETpassdeviceislimited. If the overcurrent condition exists for a longer time, the average power dissipation increases depending on the input-to-output voltage difference until the thermal shutdown circuitry turns the NFET off. Refer to Power DissipationandDeviceOperationforpowerdissipationcalculations. 7.3.5 Thermal-OverloadProtection Thermal-overload protection limits the total power dissipation in the LP5952. When the junction temperature exceeds T = 165°C typical, the shutdown logic is triggered, and the NFET is turned off, allowing the device to J cool down. After the junction temperature dropped by 20°C (temperature hysteresis) typical, the NFET is activatedagain.Thisresultsinapulsedoutputvoltageduringcontinuousthermal-overloadconditions. The thermal-overload protection is designed to protect the LP5952 in the event of a fault condition. For normal continuous operation, do not exceed the absolute maximum junction temperature rating of T = 150°C (see J AbsoluteMaximumRatings). 7.3.6 ReverseCurrentPath The internal NFET pass device in LP5952 has an inherent parasitic body diode. During normal operation, the inputvoltageishigherthantheoutputvoltage,andtheparasiticdiodeisreversebiased.However,iftheoutputis pulled above the input in an application, the current flows from the output to the input as the parasitic diode gets forwardbiased.Theoutputcanbepulledabovetheinputaslongasthecurrentintheparasiticdiodeislimitedto 50 mA. For currents above this limit an external Schottky diode must be connected from V to V (cathode on OUT IN V ,anodeonV ). IN OUT 7.4 Device Functional Modes 7.4.1 EnableOperation The LP5952 may be switched to an ON or OFF state by a logic input at the EN pin, V . A logic high at this pin EN turns the device on. When the enable pin is low, the regulator output is off, and the device typically consumes 0.1 µA. If the application does not require the enable switching feature, the EN pin must be tied to V to keep the BATT regulatoroutputpermanentlyon.

AcapacitoratV isnotrequiredifthedistancetothesupplydoesnotexceed5cm. BATT If the device is used in the typical application as post regulator after a DC-DC regulator, no input capacitors are required — the capacitors of the DC-DC regulator (C and C ) are sufficient if both components are mounted IN OUT close to each other and a proper GND plane is used. If the distance between the output capacitor of the DC-DC regulatorandtheINpinoftheLP5952islargerthan5cm,addinganinputcapacitoratV isrecommended. IN NOTE Important: Tantalum capacitors can suffer catastrophic failures due to surge current when connected to a low-impedance source of power (like a battery or a very large capacitor). If a tantalum capacitor is used at the input, it must be ensured by the manufacturertohaveasurgecurrentratingsufficientfortheapplication. The equivalent series resistance (ESR) of the input capacitor should be in the range of 3 mΩ to 300 mΩ. The tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the capacitanceremains≥ 470nFovertheentireoperatingtemperaturerange. 8.2.1.2.3 OutputCapacitor The LP5952 is designed specifically to work with very small ceramic output capacitors. A ceramic capacitor (dielectrictypesX7R,Z5U,orY5V)inthe2.2-µFrange(upto10 µF)andwithanESRbetween3mΩ to300mΩ issuitableasC intheLP5952applicationcircuit. OUT This capacitor must be located a distance of not more than 1 cm from the OUT pin and returned to a clean analogground. It is also possible to use tantalum or film capacitors at the device output, V , but these are not as attractive for OUT reasonsofsizeandcost(seeCapacitorCharacteristics). 8.2.1.2.4 CapacitorCharacteristics The LP5952 is designed to work with ceramic capacitors on the output to take advantage of the benefits they offer. For capacitance values in the 1-µF to 4.7-µF range, 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-µF ceramic capacitor is in the range of 3 mΩ to 40 mΩ, which easily meets the ESR requirement for stabilityfortheLP5952. 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 capacitortype. In particular, the output capacitor selection must take account of all the capacitor parameters, to ensure that the specification is met within the application. The capacitance can vary with DC bias conditions as well as temperature and frequency of operation. Capacitor values 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. Figure 10 shows a typical graph comparing different capacitor case sizes in a capacitancevs.DCBiasplot.AsshownFigure10,increasingtheDC-biasconditioncanresultinthecapacitance value falling below the minimum value given in Input and Output Capacitors (Recommended) (0.47 µF or 1.5 µF in this case). The graph shows the capacitance out of specification for the 0402 case size capacitor at higher bias voltages. It is therefore recommended that the capacitor-manufacturer specifications for the nominal value capacitor are consulted for all conditions, as some capacitor sizes (such as 0402) may not be suitable in the actualapplication.

TypicalVariationInCapacitancevsDCBias Capacitance of the ceramic capacitor can vary with temperature. The capacitor type X7R, which operates over a temperature range of –55°C to +125°C, only varies the capacitance to within ±15%. The capacitor type X5R has a similar tolerance over a reduced temperature range of –55°C to +85°C. Many large value ceramic capacitors, larger than 1 µF, are manufactured with Z5U or Y5V temperature characteristics. Their capacitance can drop by more than 50% as the temperature varies from 25°C to 85°C. Therefore, X7R is recommended over Z5U and Y5Vinapplicationswheretheambienttemperaturechangessignificantlyaboveorbelow25°C. Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more expensivewhencomparingequivalentcapacitanceandvoltageratingsinthe1-µFto4.7-µFrange. 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. The ESR of a typical tantalum increases about 2:1 as the temperature goes from25°Cdownto–40°C,sosomeguardbandmustbeallowed. 8.2.1.2.5 PowerDissipationandDeviceOperation The permissible power dissipation for any package is a measure of the capability of the device to pass heat from thepowersource,thejunctionsofthedevice,totheultimateheatsink,theambientenvironment.Thusthepower dissipation is dependent on the ambient temperature and the thermal resistance across the various interfaces betweenthedieandambientair.
