9 APPLICATIONS INFORMATION Introduction The NCP7 features a significant reduction in dropout voltage along with enhanced output voltage accuracy and temperature stability when compared to older industry standard threeterminal adjustable regulators. These devices contain output current limiting, safe operating area compensation and thermal shutdown protection making them designer friendly for powering numerous consumer and industrial products. The NCP7 series is pin compatible with the older LM37 and its derivative device types. Output Voltage The typical application circuits for the fixed and adjustable output regulators are shown in Figures 3 and 4. The adjustable devices are floating voltage regulators. They develop and maintain the nominal.5 V reference voltage between the output and adjust pins. The reference voltage is programmed to a constant current source by resistor R, and this current flows through R to ground to set the output voltage. The programmed current level is usually selected to be greater than the specified 5. ma minimum that is required for regulation. Since the adjust pin current, I adj, is significantly lower and constant with respect to the programmed load current, it generates a small output voltage error that can usually be ignored. For the fixed output devices R and R are included within the device and the ground current I gnd, ranges from 3. ma to 5. ma depending upon the output voltage. External Capacitors bypass capacitor C in may be required for regulator stability if the device is located more than a few inches from the power source. This capacitor will reduce the circuit s sensitivity when powered from a complex source impedance and significantly enhance the output transient response. The input bypass capacitor should be mounted with the shortest possible track length directly across the regulator s input and ground terminals. A F ceramic or tantalum capacitor should be adequate for most applications. C in 3 NCP7 Output XTXX Cout I gnd Figure 3. Fixed Output Regulator Frequency compensation for the regulator is provided by capacitor C out and its use is mandatory to ensure output stability. A minimum capacitance value of 4.7 F with an equivalent series resistance (ESR) that is within the limits of 33 m (typ) to. is required. See Figures and 3. The capacitor type can be ceramic, tantalum, or aluminum electrolytic as long as it meets the minimum capacitance value and ESR limits over the circuit s entire operating temperature range. Higher values of output capacitance can be used to enhance loop stability and transient response with the additional benefit of reducing output noise. C in 3 NCP7 Output XTA R Cout V ref I adj R Cadj Vout Vref R R I adj R Figure 4. Adjustable Output Regulator The output ripple will increase linearly for fixed and adjustable devices as the ratio of output voltage to the reference voltage increases. For example, with a V regulator, the output ripple will increase by V/.5 V or 9.6 and the ripple rejection will decrease by log of this ratio or 9.6 db. The loss of ripple rejection can be restored to the values shown with the addition of bypass capacitor C adj, shown in Figure 4. The reactance of C adj at the ripple frequency must be less than the resistance of R. The value of R can be selected to provide the minimum required load current to maintain regulation and is usually in the range of to. Cadj fripple R The minimum required capacitance can be calculated from the above formula. When using the device in an application that is powered from the AC line via a transformer and a full wave bridge, the value for C adj is: fripple Hz, R, then Cadj. F The value for C adj is significantly reduced in applications where the input ripple frequency is high. If used as a post regulator in a switching converter under the following conditions: fripple 5 khz, R, then Cadj.7 F Figures and shows the level of ripple rejection that is obtainable with the adjust pin properly bypassed. 9

10 Protection Diodes The NCP7 family has two internal low impedance diode paths that normally do not require protection when used in the typical regulator applications. The first path connects between V out and V in, and it can withstand a peak surge current of about 5 A. Normal cycling of V in cannot generate a current surge of this magnitude. Only when V in is shorted or crowbarred to ground and C out is greater than 5 F, it becomes possible for device damage to occur. Under these conditions, diode D is required to protect the device. The second path connects between C adj and V out, and it can withstand a peak surge current of about 5 ma. Protection diode D is required if the output is shorted or crowbarred to ground and C adj is greater than. F. C in D N4 3 NCP7 Output XTA R D Cout N4 R Cadj Figure 5. Protection Diode Placement A combination of protection diodes D and D may be required in the event that V in is shorted to ground and C adj is greater than 5 F. The peak current capability stated for the internal diodes are for a time of s with a junction temperature of 5 C. These values may vary and are to be used as a general guide. Load Regulation The NCP7 series is capable of providing excellent load regulation; but since these are three terminal devices, only partial remote load sensing is possible. There are two conditions that must be met to achieve the maximum available load regulation performance. The first is that the top side of programming resistor R should be connected as close to the regulator case as practicable. This will minimize the voltage drop caused by wiring resistance RW from appearing in series with reference voltage that is across R. The second condition is that the ground end of R should be connected directly to the load. This allows true Kelvin sensing where the regulator compensates for the voltage drop caused by wiring resistance RW. C in 3 NCP7 XTA RW Output R R Cout RW Figure 6. Load Sensing Remote Load Thermal Considerations This series contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 75 C, the regulator output switches off and then back on as the die cools. As a result, if the device is continuously operated in an overheated condition, the output will appear to be oscillating. This feature provides protection from a catastrophic device failure due to accidental overheating. It is not intended to be used as a substitute for proper heatsinking. The maximum device power dissipation can be calculated by: PD T J(max) TA RJA The devices are available in surface mount SOT3 and DPAK packages. Each package has an exposed metal tab that is specifically designed to reduce the junction to air thermal resistance, R JA, by utilizing the printed circuit board copper as a heat dissipater. Figures and show typical R JA values that can be obtained from a square pattern using economical single sided. ounce copper board material. The final product thermal limits should be tested and quantified in order to insure acceptable performance and reliability. The actual R JA can vary considerably from the graphs shown. This will be due to any changes made in the copper aspect ratio of the final layout, adjacent heat sources, and air flow.
