Quiescent Current (Iq) is the difference between the input current (measured through the LDO input pin) and the output load current. Output Voltage Current Limit The output voltage parameter is defined for specific temperature, input voltage and output current values or specified over Line, Load and Temperature ranges. Current Limit is value of output current by which output voltage drops 100 mV below its nominal value. It means that the device is capable to supply minimum 30 mA. Line Regulation PSRR The change in output voltage for a change in input voltage measured for specific output current over operating ambient temperature range. Power Supply Rejection Ratio is defined as ratio of output voltage and input voltage ripple. It is measured in decibels (dB). Load Regulation Thermal Protection The change in output voltage for a change in output current measured for specific input voltage over operating ambient temperature range. 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 175C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. Dropout Voltage The input to output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. It is measured when the output drops 100 mV below its nominal value. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Maximum Package Power Dissipation The power dissipation level is maximum allowed power dissipation for particular package or power dissipation at which the junction temperature reaches its maximum operating value, whichever is lower. www.onsemi.com 9 NCV4294C APPLICATIONS INFORMATION conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCV4294C can handle is given by: The NCV4294C low dropout regulator is self-protected with internal thermal shutdown and internal current limit. Typical characteristics are shown in Figure 3 to Figure 18. Input Decoupling (Cin) A ceramic or tantalum 0.1 mF capacitor is recommended and should be connected close to the NCV4294C package. Higher capacitance and lower ESR will improve the overall line and load transient response. PD(MAX) + T J(MAX) * T A (eq. 1) R qJA Since TJ is not recommended to exceed 150C, then the NCV4294C soldered on 645 mm2, 1 oz copper area, FR4 can dissipate up to 0.92 W when the ambient temperature (TA) is 25C. See Figure 18 for RthJA versus PCB area. The power dissipated by the NCV4294C can be calculated from the following equations: Output Decoupling (Cout) The NCV4294C is a stable component and does not require a minimum Equivalent Series Resistance (ESR) for the output capacitor. Stability region of ESR vs. Output Current is shown in Figures 3 and 11. The minimum output decoupling value is 2.2 mF and can be augmented to fulfill stringent load transient requirements. The regulator works with ceramic chip capacitors as well as tantalum devices. Larger values improve noise rejection and load transient response. PD [ V inIq@I out ) I outVin * Vout (eq. 2) or Vin(MAX) [ P D(MAX) ) V out I out I out ) I q (eq. 3) Thermal Considerations Hints As power in the NCV4294C 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 on the PCB, the board material, and the ambient temperature affect the rate of junction temperature rise for the part. When the NCV4294C has good thermal Vin and GND printed circuit board traces should be as wide as possible. When the impedance of these traces 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 NCV4294C and make traces as short as possible.
