Load Transient Response (10 mF) http://onsemi.com 10 NCP603 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 no−load and full−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. Ground Current Ground Current is the current that flows through the ground pin when the regulator operates without a load on its output (IGND). 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 standby current (ISTBY.) Maximum Package Power Dissipation The power dissipation level at which the junction temperature reaches its maximum operating value. APPLICATIONS INFORMATION output, there is no resistor divider. If the part is enabled under no−load conditions, leakage current through the pass transistor at junction temperatures above 85°C can approach several microamperes, especially as junction temperature approaches 150°C. If this leakage current is not directed into a load, the output voltage will rise up to a level approximately 20 mV above nominal. The NCP603 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. When the NCP603 adjustable regulator is disabled, the overshoot clamp circuit becomes inactive and the pass transistor leakage will charge any capacitance on Vout. If no load is present, the output can charge up to within a few millivolts of Vin. In most applications, the load will present some impedance to Vout such that the output voltage will be inherently clamped at a safe level. A minimum load of 10 mA is recommended. The NCP603 series regulator is self−protected with internal thermal shutdown and internal current limit. Typical application circuits are shown in Figures 2 and 3. Input Decoupling (Cin) A ceramic or tantalum 1.0 mF capacitor is recommended and should be connected close to the NCP603 package. Higher capacitance and lower ESR will improve the overall line transient response. Output Decoupling (Cout) The NCP603 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. Larger values improve noise rejection and load regulation transient response. Figure 28 shows the stability region for a range of operating conditions and ESR values. No−Load Regulation Considerations The NCP603 adjustable regulator will operate properly under conditions where the only load current is through the resistor divider that sets the output voltage. However, in the case where the NCP603 is configured to provide a 1.250 V http://onsemi.com 11 NCP603 Noise Decoupling Thermal The NCP603 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 NCP603 operates without a noise reduction capacitor, has a typical 15 ms start up delay and achieves a 50 mVrms overall noise level between 10 Hz and 100 kHz. As power in the NCP603 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 NCP603 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCP603 can handle is given by: Enable Operation 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. PD(MAX) + The output voltage can be adjusted from 1 times (Figure 2) to 4 times (Figure 3) the typical 1.250 V regulation voltage via the use of resistors between the output and the ADJ input. The output voltage and resistors are chosen using Equation 1 and Equation 2. ǒ Ǔ ƪ ƫ R1) PD [ VIN(IGND@IOUT) ) IOUT(VIN * VOUT) (eq. 4) or VIN(MAX) [ (eq. 1) ƪ (eq. 3) Since TJ is not recommended to exceed 125_C (TJ(MAX)), then the NCP603 can dissipate up to 465 mW when the ambient temperature (TA) is 25_C and the device is assembled on 1 oz PCB with 645 mm2 area. The power dissipated by the NCP603 can be calculated from the following equations: Output Voltage Adjust VOUT + 1.250 1 ) R1 ) (IADJ R2 TJ(MAX) * TA RqJA ƫ [Vout * (IADJ * R1)] V * 1 ^ R2 out * 1 R1 + R2 * 1.25 1.25 PD(MAX) ) (VOUT IOUT) IOUT ) IGND (eq. 5) 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 NCP603, and make traces as short as possible. (eq. 2) Input bias current IADJ is typically less than 150 nA. Choose R2 arbitrarily t minimize errors due to the bias current and to minimize noise contribution to the output voltage. Use Equation 2 to find the required value for R1.
