LP2950,LP2951 SLVS582I–APRIL2006–REVISEDNOVEMBER2014 www.ti.com 7 Detailed Description 7.1 Overview The LP2950 and LP2951 devices are bipolar, low-dropout voltage regulators that can accommodate a wide input supply-voltage range of up to 30 V. The easy-to-use, 3-pin LP2950 is available in fixed-output voltages of 5 V, 3.3 V, and 3 V. However, the 8-pin LP2951 device is able to output either a fixed or adjustable output from the same device. By tying the OUTPUT and SENSE pins together, and the FEEDBACK and V pins together, the TAP LP2951deviceoutputsafixed5V,3.3V,or3V(dependingontheversion).Alternatively,byleavingtheSENSE and V pins open and connecting FEEDBACK to an external resistor divider, the output can be set to any TAP valuebetween1.235Vto30V. The 8-pin LP2951 device also offers additional functionality that makes it particularly suitable for battery-powered applications. For example, a logic-compatible shutdown feature allows the regulator to be put in standby mode for power savings. In addition, there is a built-in supervisor reset function in which the ERROR output goes low when V drops by 6% of its nominal value for whatever reasons – due to a drop in V , current limiting, or OUT IN thermalshutdown. The LP2950 and LP2951 devices are designed to minimize all error contributions to the output voltage. With a tight output tolerance (0.5% at 25°C), a very low output voltage temperature coefficient (20 ppm typical), extremely good line and load regulation (0.3% and 0.4% typical), and remote sensing capability, the parts can be usedaseitherlow-powervoltagereferencesor100-mAregulators. 7.2 LP2950 Functional Block Diagram INPUT OUTPUT + Error Amplifier 1.23-V Reference GND 12 SubmitDocumentationFeedback Copyright©2006–2014,TexasInstrumentsIncorporated ProductFolderLinks:LP2950 LP2951

This 95% of nominal figure is obtained by dividing the built-in offset of ≈60 mV by the 1.235-V bandgap reference, and remains independent of the programmed output voltage. For example, the trip-point threshold (ERROR output goes high) typically is 4.75 V for a 5-V output and 11.4 V for a 12-V output. Typically, there is a hysteresisof15mVbetweenthethresholdsforhighandlow ERROR output. A timing diagram is shown in Figure 31 for ERROR vs V (5 V), as V is ramped up and down. ERROR OUT IN becomes valid (low) when V ≈ 1.3 V. When V ≈ 5 V, V = 4.75 V, causing ERROR to go high. Because the IN IN OUT dropout voltage is load dependent, the output trip-point threshold is reached at different values of V , depending IN on the load current. For instance, at higher load current, ERROR goes high at a slightly higher value of V , and IN vice versa for lower load current. The output-voltage trip point remains at ~4.75 V, regardless of the load. Note that when V ≤ 1.3 V, the ERROR comparator output is turned off and pulled high to its pullup voltage. If V is IN OUT used as the pullup voltage, rather than an external 5-V source, ERROR typically is ~1.2 V. In this condition, an equal resistor divider (10 kΩ is suitable) can be tied to ERROR to divide down the voltage to a valid logic low duringanyfaultcondition,whilestillenablingalogichighduringnormaloperation. Output 4.75 V Voltage ERROR Input 5 V Voltage 1.3 V Figure31. ERROR OutputTiming Because the ERROR comparator has an open-collector output, an external pullup resistor is required to pull the output up to V or another supply voltage (up to 30 V). The output of the comparator is rated to sink up to OUT 400 μA. A suitable range of values for the pullup resistor is from 100 kΩ to 1 MΩ. If ERROR is not used, it can beleftopen. 14 SubmitDocumentationFeedback Copyright©2006–2014,TexasInstrumentsIncorporated ProductFolderLinks:LP2950 LP2951

Consequently, a larger capacitance is needed for stability. For V = 3 V or 3.3 V, a minimum of 2.2 μF is recommended. For worst case, V = 1.23 V (using the ADJ OUT OUT version), a minimum of 3.3 μF is recommended. C can be increased without limit and only improves the OUT regulator stability and transient response. Regardless of its value, the output capacitor should have a resonant frequencygreaterthan500kHz. The minimum capacitance values given above are for maximum load current of 100 mA. If the maximum expectedloadcurrentislessthan100mA,thenlowervaluesofC canbeused.Forinstance,ifI <10mA, OUT OUT then only 0.33 μF is required for C . For I < 1 mA, 0.1 μF is sufficient for stability requirements. Thus, for a OUT OUT worst-case condition of 100-mA load and V = V = 1.235 V (representing the highest load current and OUT REF lowestloopgain),aminimumC of3.3μFisrecommended. OUT For the LP2950/51, no load stability is inherent in the design — a desirable feature in CMOS circuits that are put in standby (such as RAM keep-alive applications). If the LP2951 is used with external resistors to set the output voltage,aminimumloadcurrentof1μAisrecommendedthroughtheresistordivider. 8.2.2.2 CapacitorTypes Most tantalum or aluminum electrolytics are suitable for use at the input. Film-type capacitors also work but at higher cost. When operating at low temperature, care should be taken with aluminum electrolytics, as their electrolytes often freeze at –30°C. For this reason, solid tantalum capacitors should be used at temperatures below–25°C. Ceramic capacitors can be used, but due to their low ESR (as low as 5 mΩ to 10 mΩ), they may not meet the minimum ESR requirement previously discussed. If a ceramic capacitor is used, a series resistor between 0.1 Ω to 2 Ω must be added to meet the minimum ESR requirement. In addition, ceramic capacitors have one glaring disadvantage that must be taken into account — a poor temperature coefficient, where the capacitance can vary significantly with temperature. For instance, a large-value ceramic capacitor (≥ 2.2 μF) can lose more than half of its capacitance as temperature rises from 25°C to 85°C. Thus, a 2.2-μF capacitor at 25°C drops well below the minimum C required for stability as ambient temperature rises. For this reason, select an output OUT capacitorthatmaintainstheminimum2.2μFrequiredforstabilityfortheentireoperatingtemperaturerange. 8.2.2.3 C :NoiseandStabilityImprovement BYPASS In the LP2951 device, an external FEEDBACK pin directly connected to the error amplifier noninverting input can allow stray capacitance to cause instability by shunting the error amplifier feedback to GND, especially at high frequencies. This is worsened if high-value external resistors are used to set the output voltage, because a high resistance allows the stray capacitance to play a more significant role; i.e., a larger RC time delay is introduced between the output of the error amplifier and its FEEDBACK input, leading to more phase shift and lower phase margin. A solution is to add a 100-pF bypass capacitor (C ) between OUTPUT and FEEDBACK; because BYPASS C is in parallel with R1, it lowers the impedance seen at FEEDBACK at high frequencies, in effect BYPASS offsetting the effect of the parasitic capacitance by providing more feedback at higher frequencies. More feedback forces the error amplifier to work at a lower loop gain, so C should be increased to a minimum of OUT 3.3 μFtoimprovetheregulator’sphasemargin. C can be also used to reduce output noise in the LP2951 device. This bypass capacitor reduces the BYPASS closed loop gain of the error amplifier at the high frequency, so noise no longer scales with the output voltage. This improvement is more noticeable with higher output voltages, where loop gain reduction is greatest. A suitableC iscalculatedasshowninEquation2: BYPASS 1 f ; 200Hz®C = (CBYPASS) (BYPASS) 2p´R1´200Hz (2) On the 3-pin LP2950 device, noise reduction can be achieved by increasing the output capacitor, which causes the regulator bandwidth to be reduced, thus eliminating high-frequency noise. However, this method is relatively inefficient, as increasing C from 1 μF to 220 μF only reduces the regulator’s output noise from OUT 430μVto160 μV(overa100-kHzbandwidth).

LP2950,LP2951 SLVS582I–APRIL2006–REVISEDNOVEMBER2014 www.ti.com Typical Application (continued) 8.2.2.4 ESRRange The regulator control loop relies on the ESR of the output capacitor to provide a zero to add sufficient phase margin to ensure unconditional regulator stability; this requires the closed-loop gain to intersect the open-loop response in a region where the open-loop gain rolls off at 20 dB/decade. This ensures that the phase is always less than 180° (phase margin greater than 0°) at unity gain. Thus, a minimum-maximum range for the ESR must beobserved. The upper limit of this ESR range is established by the fact that an ESR that is too high could result in the zero occurring too soon, causing the gain to roll off too slowly. This, in turn, allows a third pole to appear before unity gain and introduces enough phase shift to cause instability. This typically limits the maximum ESR to approximately5 Ω. Conversely, the lower limit of the ESR range is tied to the fact that an ESR that is too low shifts the zero too far out, past unity gain, which allows the gain to roll off at 40 dB/decade at unity gain, resulting in a phase shift of greaterthan180°.Typically,thislimitstheminimumESRtoapproximately20mΩ to30mΩ.
