80 mA CMOS Low Iq
NOCAPE Voltage Regulator
This series of fixed output NOCAP linear regulators are designed
for handheld communication equipment and portable battery powered
applications which require low quiescent. This series features an
ultra−low quiescent current of 2.8 mA. 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.
These voltage regulators have been designed to be used with low
cost ceramic capacitors. The devices have the ability to operate
without an output capacitor. The devices are 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. Other voltages
are available in 100 mV steps.

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
Thermal
A typical application circuit for the NCP553 series is
shown in Figure 1, front page.
As power across the NCP553 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 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:
Input Decoupling (C1)
A 1.0 mF capacitor either ceramic or tantalum is
recommended and should be connected close to the package.
Higher values and lower ESR will improve the overall line
transient response. If large line or load transients are not
expected, then it is possible to operate the regulator without
the use of a capacitor.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
T
*TA
PD + J(max)
RqJA
The NCP553 are very stable regulators and do not require
any specific Equivalent Series Resistance (ESR) or a
minimum output current. If load transients are not to be
expected, then it is possible for the regulator to operate with
no output capacitor. Otherwise, capacitors exhibiting ESRs
ranging from a few mW up to 10 Wcan thus safely be used.
The minimum decoupling value is 0.1 mF 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
If junction temperature is not allowed above the
maximum 125C, then the NCP553 can dissipate up to
250 mW @ 25C.
The power dissipated by the NCP553 can be calculated
from the following equation:
Ptot + ƪVin * Ignd (Iout)ƫ ) [Vin * Vout] * Iout
or
P ) Vout * Iout
VinMAX + tot
Ignd ) Iout
If an 80 mA output current is needed then the ground
current from the data sheet is 2.8 mA. For an NCP553
(3.0 V), the maximum input voltage will then be 6.12 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.
Set external components, especially the output capacitor,
as close as possible to the circuit, and make leads as short as
possible.
