NCP612, NCV612
100 mA CMOS Low Iq
Voltage Regulator in an
SC70-5
The NCP612/NCV612 series of fixed output linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. The
NCP612/NCV612 series features an ultra−low quiescent current of
40 A. Each device contains a voltage reference unit, an error
amplifier, a PMOS power transistor, resistors for setting output
voltage, current limit, and temperature limit protection circuits.
The NCP612/NCV612 has been designed to be used with low cost
ceramic capacitors. The device is housed in the micro−miniature
SC70−5 surface mount package. Standard voltage versions are 1.5,
1.8, 2.5, 2.7, 2.8, 3.0, 3.1, 3.3, 3.7, and 5.0 V.

DEFINITIONS
Load Regulation
Line Regulation
The change in output voltage for a change in output
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 technique such that the average
chip 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 3.0% below
its nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Line Transient Response
Typical over and undershoot response when input voltage
is excited with a given slope.
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 160C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.
Maximum Power Dissipation
The maximum total dissipation for which the regulator
will operate within its specifications.
Quiescent Current
The quiescent current is the current which flows through
the ground when the LDO operates without a load on its
output: internal IC operation, bias, etc. When the LDO
becomes loaded, this term is called the Ground current. It is
actually the difference between the input current (measured
through the LDO input pin) and the output current.
Maximum Package Power Dissipation
The maximum power package dissipation is the power
dissipation level at which the junction temperature reaches
its maximum operating value, i.e. 150C. Depending on the
ambient power dissipation and thus the maximum available
output current.

APPLICATIONS INFORMATION
Thermal
A typical application circuit for the NCP612/NCV612 is
shown in Figure 1, front page.
As power across the NCP612/NCV612 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 also the
ambient temperature effect the rate of temperature rise for
the part. This is stating that when the NCP612/NCV612 has
good thermal conductivity through the PCB, the junction
temperature will be relatively low with high power
dissipation applications.
The maximum dissipation the package can handle is
given by:
Input Decoupling (C1)
A 1.0 F capacitor either ceramic or tantalum is
recommended and should be connected close to the
NCP612/NCV612 package. Higher values and lower ESR
will improve the overall line transient response.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP612/NCV612 is a stable regulator and does not
require any specific Equivalent Series Resistance (ESR) or
a minimum output current. Capacitors exhibiting ESRs
ranging from a few m up to 5.0 can thus safely be used.
The minimum decoupling value is 1.0 F and can be
augmented to fulfill stringent load transient requirements.
The regulator accepts ceramic chip capacitors as well as
tantalum capacitors. Larger values improve noise rejection
and load regulation transient response.
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,
or C3216X7R1C105K
T
*TA
PD + J(max)
RJA
If junction temperature is not allowed above the
maximum 125C, then the NCP612/NCV612 can dissipate
up to 330 mW @ 25C.
The power dissipated by the NCP612/NCV612 can be
calculated from the following equation:
Ptot + ƪVin * Ignd (Iout)ƫ ) [Vin * Vout] * Iout
Enable Operation
or
The enable pin will turn on the regulator when pulled high
and turn off the regulator when pulled low. These limits of
threshold are covered in the electrical specification section
of this data sheet. If the enable is not used then the pin should
be connected to Vin.
P ) Vout * Iout
VinMAX + tot
Ignd ) Iout
If an 100 mA output current is needed then the ground
current from the data sheet is 40 A. For an
NCP612/NCV612 (3.0 V), the maximum input voltage will
then be 6.0 V (Limited by maximum input voltage).
Hints
Please be sure the Vin and Gnd lines are sufficiently wide.
When the impedance of these lines is high, there is a chance
to pick up noise or cause the regulator to malfunction.
Set external components, especially the output capacitor,
as close as possible to the circuit, and make leads as short as
possible.
