Results are expressed in mVrms or nV / Hz. All measurements are performed using short pulse low duty cycle techniques to maintain junction temperature as close as possible to ambient temperature. Turn-on and Turn-off Times 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. 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. Load Regulation The change in output voltage for a change in output load current at a constant temperature. Dropout Voltage Enable and Disable Times 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. 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 moment when output voltage drops to 10% of its nominal value at specific output current or resistive load. 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). Line Transient Response Typical output voltage overshoot and undershoot response when the input voltage is excited with a given slope. Load 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. 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. Short Circuit Current Limit is output current value measured with output of the regulator shorted to ground. 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 175C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. PSRR Power Supply Rejection Ratio is defined as ratio of output voltage and input voltage ripple. It is measured in decibels (dB). Maximum Package Power Dissipation Output Noise Voltage The power dissipation level at which the junction temperature reaches its maximum operating value. This is the integrated value of the output noise over a specified frequency range. Input voltage and output load http://onsemi.com 9 NCP605, NCP606 APPLICATIONS INFORMATION Noise Decoupling The NCP605/NCP606 regulator is self*protected with internal thermal shutdown and internal current limit. Typical application circuits are shown in Figures 1 to 4. The NCP605/NCP606 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 NCP605/NCP606 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. Input Decoupling (Cin) A ceramic or tantalum 1.0 mF capacitor is recommended and should be connected close to the NCP605/NCP606 package. Higher capacitance and lower ESR will improve the overall line transient response. Enable Operation (NCP606 Only) Output Decoupling (Cout) 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 NCP605/NCP606 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). 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. No-Load Regulation Considerations The NCP605/NCP606 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 NCP605/NCP606 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 85C can approach several microamps, especially as junction temperature approaches 150C. 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 NCP605/ NCP606 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 (NCP606 only) 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 NCP606 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 NCP605/606 fixed voltage versions there is no limitation for minimum load current. V out + 1.250 1 ) R2 ^ R1 R2 ) I ADJ R 1 (eq. 1) R1 V out 1.25 *1 (eq. 2) 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. Thermal As power in the NCP605/NCP606 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 NCP605/NCP606 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCP605/NCP606 can handle is given by: P D(MAX) + TJ(MAX) * TA (eq. 3) R QJA Since TJ is not recommended to exceed 125C (TJ(MAX)), then the NCP605/NCP606 soldered on 645 mm2, 1 oz copper area, FR4 can dissipate up to 1.3 W when the ambient http://onsemi.com 10 NCP605, NCP606 Hints temperature (TA) is 25C. See Figure 23 for RqJA versus PCB area. The power dissipated by the NCP605/NCP606 can be calculated from the following equations: P D [ V inI GND@I OUT ) I outV in * V out 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.
