DEFINITIONS
Load Regulation Line Regulation
The change in output voltage for a change in output load current at a constant temperature.
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.
Output Noise Voltage
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.
Line Transient Response
Typical output voltage overshoot and undershoot response when the input voltage is excited with a given slope.
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.
Ground Current
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
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).
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.
Maximum Package Power Dissipation
The power dissipation level at which the junction temperature reaches its maximum operating value.
APPLICATIONS INFORMATION The NCV8560 series regulator is self-protected with internal thermal shutdown and internal current limit. Typical application circuits are shown in Figures 4 and 5.
Input Decoupling (Cin)
A ceramic or tantalum 1.0 mF capacitor is recommended and should be connected close to the NCV8560 package. Higher capacitance and lower ESR will improve the overall line transient response. The NCV8560 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 30 shows the stability region for a range of operating conditions and ESR values. The NCV8560 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 NCV8560 is configured to provide a 1.250
Output Decoupling (Cout)
No-Load Regulation Considerations
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 NCV8560 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 NCV8560 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.

NCV8560
Noise Decoupling
The NCV8560 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 NCV8560 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.
Enable Operation
600 mW when the ambient temperature (TA) is 25C, and PCB area is 150mm2 and larger, see Figure 33. The power dissipated by the NCV8560 can be calculated from the following equations:
P D [ V in I GND @ I out ) I out V in * V out (eq. 4)
or
V in(MAX) [ P D(MAX) ) V out I out ) I GND I out (eq. 5)
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.
Output Voltage Adjust
If a 150 mA output current is needed, the quiescent current IGND is taken from the data sheet electrical characteristics table or extracted from Figure 20 and Figure 22. IGND is approximately 108 mA when Iout = 150 mA. For an output voltage of 1.250 V, the maximum input voltage will then be 3.9 V, good for a 1 Cell Li-ion battery.
RthJA, THERMAL RESISTANCE JUNCTION-TO-AMBIENT (C/W)
The output voltage can be adjusted from 1 times (Figure 4) to 4 times (Figure 5) 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.

Input bias current IADJ is typically less than 150 nA. Choose R2 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 R1.

Figure 33. RthJA vs. PCB Copper Area
As power in the NCV8560 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 NCV8560 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power applications. The maximum dissipation the NCV8560 can handle is given by:
PD(MAX) + TJ(MAX) * TA RqJA (eq. 3)
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 NCV8560, and make traces as short as possible.
Since TJ is not recommended to exceed 125C (TJ(MAX)), then the NCV8560 in a DFN6 package can dissipate up to
