Load Transient Response (10 mF) http://onsemi.com 8 NCP629 DEFINITIONS Load Regulation Line Regulation The change in output voltage for a change in output load 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 techniques such that the average junction 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 2% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Line Transient Response Typical output voltage overshoot and undershoot response when the input voltage is excited with a given slope. Output Noise Voltage Load Transient Response This is the integrated value of the output noise over a specified frequency range. Input voltage and output load current are kept constant during the measurement. Results are expressed in mVrms or nV/√Hz. Typical output voltage overshoot and undershoot response when the output current is excited with a given slope between low-load and high-load conditions. 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 175°C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. Disable and Ground Current Ground Current (IGND) is the current that flows through the ground pin when the regulator operates with a load on its output. This consists of internal IC operation, bias, etc. It is actually the difference between the input current (measured through the LDO input pin) and the output load current. If the regulator has an input pin that reduces its internal bias and shuts off the output (enable/disable function), this term is called the disable current (IDIS.) Maximum Package Power Dissipation The power dissipation level at which the junction temperature reaches its maximum operating value. APPLICATIONS INFORMATION The NCP629 series regulator is self-protected with internal thermal shutdown and internal current limit. Typical application circuit is shown in Figure 1. characteristics were measured with Murata ceramic capacitors GRM31MR71E105KA01 (1.0 mF, 25 V X7R, 1206). Larger values improve noise rejection and load regulation transient response. Figure 23 shows the stability region for a range of operating conditions and ESR values. Input Decoupling (Cin) A ceramic or tantalum 1.0 mF capacitor is recommended and should be connected close to the NCP629 package. Higher capacitance and lower ESR will improve the overall line transient response. No-Load Regulation Considerations The NCP629 contains an overshoot clamp circuit to improve transient response during a load current step release. When output voltage exceeds the nominal by approximately 20 mV, this circuit becomes active and clamps the output from further voltage increase. Tying the ENABLE pin to Vin will ensure that the part is active whenever the supply voltage is present, thus guaranteeing that the clamp circuit is active whenever leakage current is present. Output Decoupling (Cout) The NCP629 is a stable component and does not require a minimum Equivalent Series Resistance (ESR) for the output capacitor. The minimum output decoupling value is 1.0 mF and can be augmented to fulfill stringent load transient requirements. The regulator works with ceramic chip capacitors as well as tantalum devices. Typical http://onsemi.com 9 NCP629 Noise Decoupling The power dissipated by the NCP629 can be calculated from the following equations: The NCP629 is a low noise regulator and needs no external noise reduction capacitor. Unlike other low noise regulators which require an external capacitor and have slow startup times, the NCP629 operates without a noise reduction capacitor, has a typical 15 ms startup delay and achieves a 50 mVrms overall noise level between 10 Hz and 100 kHz. P D [ V inǒI GND@I outǓ ) I outǒV in * V outǓ (eq. 2) or Vin(MAX) [ PD(MAX) ) (Vout Iout) Iout ) IGND (eq. 3) Enable Operation RthJA, THERMAL RESISTANCE JUNCTION-TO-AMBIENT (°C/W) The enable pin will turn the regulator on or off. The threshold limits are covered in the electrical characteristics table in this data sheet. The turn-on/turn-off transient voltage being supplied to the enable pin should exceed a slew rate of 10 mV/ms to ensure correct operation. If the enable function is not to be used then the pin should be connected to Vin. Thermal As power in the NCP629 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 NCP629 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCP629 can handle is given by: PD(MAX) + TJ(MAX) * TA RqJA (eq. 1) Since TJ is not recommended to exceed 125_C, then the NCP629 soldered on 645 mm2, 1 oz copper area, FR4 can dissipate up to 360 mW when the ambient temperature (TA) is 25_C. See Figure 26 for RthJA versus PCB area. 340 320 300 (1 oz) 280 260 (2 oz) 240 220 200 0 100 200 300 400 500 PCB COPPER AREA (mm2) 600 700 Figure 26. RthJA vs. PCB Copper Area Hints 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 NCP629, and make traces as short as possible.
