100 mA CMOS Low Iq
Low−Dropout Voltage
Regulator
This series of fixed output low−dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent current. This series
features an ultra−low quiescent current of 2.5 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 NCP662/NCV662 series
provides an enable pin for ON/OFF control.
This series has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 F. The
device is housed in the micro−miniature SC82−AB surface mount
package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3,
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. 125°C. Depending on the
ambient power dissipation and thus the maximum available
output current.

APPLICATIONS INFORMATION
A typical application circuit for the NCP662/NCV662
and NCP663/NCV663 series are shown in Figure 1 and
Figure 2.
Place external components, especially the output
capacitor, as close as possible to the circuit, and make leads
as short as possible.
Input Decoupling (C1)
Thermal
A 1.0 F capacitor, either ceramic or tantalum is
recommended and should be connected close to the device
package. Higher capacitance values and lower ESR will
improve the overall line transient response.
TDK capacitor: C2012X5R1C105K or C1608X5R1A105K
As power across the NCP662/NCV662 and
NCP663/NCV663 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. The mounting pad configuration on the
PCB, the board material, and the ambient temperature effect
the rate of temperature rise for the part. This is stating that
when the devices have 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:
Output Decoupling (C2)
The NCP662/NCV662 and NCP663/NCV663 are very
stable regulators and do not require any specific Equivalent
Series Resistance (ESR) or a minimum output current.
Capacitors exhibiting ESRs ranging from a few m up to
10 can safely be used. The minimum decoupling value is
0.1 F and can be augmented to fulfill stringent load
transient requirements. The regulator accepts ceramic chip
capacitors as well as tantalum devices. 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 NCP662/NCV662 and
NCP663/NCV663 can dissipate up to 300 mW @ 25°C.
The power dissipated by the NCP662/NCV662 and
NCP663/NCV663 can be calculated from the following
equation:
Enable Operation (NCP662/NCV662 ONLY)
The enable pin will turn on the regulator when pulled high
and turn off the regulator when pulled low. The threshold
limits are covered in the electrical specification section of
the data sheet. If the enable is not used, the pin should be
connected to Vin.
Ptot [Vin * Ignd (Iout)] [Vin Vout] * Iout
or
P Vout * Iout
VinMAX tot
Ignd Iout
If an 100 mA output current is needed then the ground
current from the data sheet is 2.5 A. For the
NCP662/NCV662 or NCP663/NCV663 (3.0 V), the
maximum input voltage is 6.0 V.
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.
