DEFINITIONS

Load 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

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.

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).

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.

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.

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.

Maximum Package Power Dissipation

The power dissipation level at which the junction

temperature reaches its maximum operating value.

APPLICATIONS INFORMATION

The NCP600 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 NCP600 package.

Higher capacitance and lower ESR will improve the overall

line transient response.

Output Decoupling (Cout)

The NCP600 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.

No−Load Regulation Considerations

The NCP600 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 NCP600 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 NCP600 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 NCP600 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.

NCP600

http://onsemi.com

Noise Decoupling

The NCP600 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 NCP600 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

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

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.

Vout

1.25 *1(eq. 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.

Thermal

As power in the NCP600 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 NCP600 has good thermal conductivity through the

PCB, the junction temperature will be relatively low with

high power applications. The maximum dissipation the

NCP600 can handle is given by:

PD(MAX) +TJ(MAX) *TA

RqJA (eq. 3)

Since TJ is not recommended to exceed 125°C (TJ(MAX)),

then the NCP600 in a DFN6 package can dissipate up to

870 mW when the ambient temperature (TA) is 25°C, and

PCB area is 640 mm2 and larger, see Figure 33.

The power dissipated by the NCP600 can be calculated

from the following equations:

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 NCP600, and

make traces as short as possible.
