Output Voltage Noise DEFINITIONS Load Regulation Line Regulation The change in output voltage for a change in output current at a constant temperature. The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected. Dropout Voltage The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 3.0% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Line Transient Response Typical over and undershoot response when input voltage is excited with a given slope. Thermal Protection Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated at typically 160°C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. Maximum Power Dissipation The maximum total dissipation for which the regulator will operate within its specifications. Quiescent Current The quiescent current is the current which flows through the ground when the LDO operates without a load on its output: internal IC operation, bias, etc. When the LDO becomes loaded, this term is called the Ground current. It is actually the difference between the input current (measured through the LDO input pin) and the output current. Maximum Package Power Dissipation The maximum power package dissipation is the power dissipation level at which the junction temperature reaches its maximum operating value, i.e. 125°C. Depending on the ambient power dissipation and thus the maximum available output current. http://onsemi.com 6 NCP698 APPLICATIONS INFORMATION A typical application circuit for the NCP698 is shown in Figure 1. on the PCB, the board material and also the ambient temperature effect the rate of temperature rise for the part. This is stating that when the devices have good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. The maximum dissipation the package can handle is given by: Input Decoupling (C1) A 1.0 F capacitor either ceramic or tantalum is recommended and should be connected close to the NCP698 package. Higher values and lower ESR will improve the overall line transient response. TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K T *TA PD + J(max) RJA Output Decoupling (C2) If junction temperature is not allowed above the maximum 125°C, then the NCP698 can dissipate up to 250 mW @ 25°C. The power dissipated by the NCP698 can be calculated from the following equation: The NCP698 is a very stable regulator and does not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few m up to 10 can thus safely be used. The minimum decoupling value is 0.1 F and can be augmented to fulfill stringent load transient requirements. The regulator accepts ceramic chip capacitors as well as tantalum devices. Larger values improve noise rejection and load regulation transient response. TDK capacitor: C2012X5R1C105K, C1608X5R1A105K, or C3216X7R1C105K Ptot + [Vin * Ignd(Iout)] ) [Vin * Vout] * Iout or P ) Vout * Iout VinMAX + tot Ignd ) Iout If an 80 mA output current is needed then the ground current from the data sheet is 2.5 A. For an NCP698 (3.0 V), the maximum input voltage will then be 6.0 V. Enable Operation The enable pin will turn on the regulator when pulled high and turn off the regulator when pulled low. These limits of threshold are covered in the electrical specification section of this data sheet. If the enable is not used, then the pin should be connected to Vin. 350 330 310 290 JA (C/W) Hints Please be sure the Vin and GND lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction. Place external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. 270 No pin connected to Cu Plane 250 230 210 190 Pin 2 connected to Cu Plane 170 150 0 Thermal 100 200 300 400 500 PCB COPPER AREA (mm2) As power across the NCP698 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration Figure 12.
