Line Transient (Vout = 2.5 V) Figure 22. Startup Transient (Vout = 2.5 V) DEFINITIONS General Short Circuit Current Limit is output current value measured with output of the regulator shorted to ground. All measurements are performed using short pulse low duty cycle techniques to maintain junction temperature as close as possible to ambient temperature. PSRR Power Supply Rejection Ratio is defined as ratio of output voltage and input voltage ripple. It is measured in decibels (dB). Line Regulation 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. Output Noise Voltage 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. Load Regulation The change in output voltage for a change in output load current at a constant temperature. Turn−on and Turn−off Times Dropout Voltage Turn−on Time is time difference measured during power−up of the device from the moment when input voltage reaches 90% of its operating value to the moment when output voltage reaches 90% of its nominal value at specific output current or resistive load. Turn−off Time is time difference measured during power−down of the device from the moment when input voltage drops to 10% of its operating value to the moment when output voltage drops to 10% of its nominal value at specific output current or resistive load. The input to output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. 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. Ground and Disable Currents 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 disable current (IDIS). Enable and Disable Times Enable Time is time difference measured during power−up of the device from the moment when enable voltage reaches 90% of input voltage operating value to the moment when output voltage reaches 90% of its nominal value at specific output current or resistive load. Disable Time is time difference measured during power−down of the device from the moment when enable voltage drops to 10% of input voltage operating value to the Current Limit and Short Circuit Current Limit Current Limit is value of output current by which output voltage drops by 10% with respect to its nominal value. www.onsemi.com 8 NCV8605, NCV8606 Thermal Protection moment when output voltage drops to 10% of its nominal value at specific output current or resistive load. Typical output voltage overshoot and undershoot response when the input voltage is excited with a given slope. 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. Load Transient Response Maximum Package Power Dissipation Line Transient Response Typical output voltage overshoot and undershoot response when the output current is excited with a given slope between no−load and full−load conditions. The power dissipation level at which the junction temperature reaches its maximum operating value. APPLICATIONS INFORMATION guaranteeing that the clamp circuit is active whenever leakage current is present. When the NCV8606 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. Unlike LP8345, for NCV8605/606 fixed voltage versions there is no limitation for minimum load current. The NCV8605/NCV8606 regulator is self−protected with internal thermal shutdown and internal current limit. Typical application circuits are shown in Figures 1 to 4. Input Decoupling (Cin) A ceramic or tantalum 1.0 mF capacitor is recommended and should be connected close to the NCV8605/NCV8606 package. Higher capacitance and lower ESR will improve the overall line transient response. Output Decoupling (Cout) The NCV8605/NCV8606 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. Typical characteristics were measured with Murata ceramic capacitors. GRM219R71E105K (1 mF, 25 V, X7R, 0805) and GRM21BR71A106K (10 mF, 10 V, X7R, 0805). Noise Decoupling The NCV8605/NCV8606 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 NCV8605/NCV8606 operates without a noise reduction capacitor, has a typical 8 ms turn−on time and achieves a 50 mVrms overall noise level between 10 Hz and 100 kHz. Enable Operation (NCV8606 Only) No−Load Regulation Considerations 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. The NCV8605/NCV8606 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 NCV8605/NCV8606 is configured to provide a 1.250 V 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 microamps, 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 NCV8605/ NCV8606 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 (NCV8606 only) will ensure that the part is active whenever the supply voltage is present, thus Output Voltage Adjust The output voltage can be adjusted from 1 times (Figure 4) 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 V out + 1.250 1 ) R2 ^ Ǔ R1 R2 9 R 1Ǔ (eq. 1) R1 V out 1.25 www.onsemi.com ) ǒI ADJ *1 (eq. 2) NCV8605, NCV8606 250 Input bias current IADJ is typically less than 150 nA. Choose R1 arbitrarily to 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 R2. RqJA, (°C/W) 200 Thermal As power in the NCV8605/NCV8606 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 NCV8605/NCV8606 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCV8605/NCV8606 can handle is given by: P D(MAX) + ƪTJ(MAX) * TAƫ FR4 = 2.0 oz 0 I out ) I GND 400 600 800 Hints (eq. 3) I outǓ 200 Figure 23. Thermal Resistance vs. Copper Area 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.
