Regulator
www.onsemi.com
This series of fixed output low−dropout 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 2.5 ꢀ 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 NCP562 series provides an
enable pin for ON/OFF control.
The NCP562/NCP563 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, 2.1, 2.5, 2.7, 2.8, 3.0,
3.3, 3.5 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
A typical application circuit for the NCP562 and NCP563
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)
A 1.0 ꢀ F capacitor either ceramic or tantalum is
recommended and should be connected close to the NCP562
package. Higher values and lower ESR will improve the
overall line transient response.
Thermal
As power across the NCP562 and NCP563 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.
TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP562 and NCP563 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 mꢂ up to 10 ꢂ can thus 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.
The maximum dissipation the package can handle is
given by:
T
*T
A
ꢁJA
J(max)
PD +
R
If junction temperature is not allowed above the
maximum 125°C, then the NCP562 and NCP563 can
dissipate up to 250 mW @ 25°C.
The power dissipated by the NCP562 and NCP563 can be
calculated from the following equation:
TDK capacitor: C2012X5R1C105K, C1608X5R1A105K,
or C3216X7R1C105K
Enable Operation (NCP562 ONLY)
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

Hints
If an 80 mA output current is needed then the ground
current from the data sheet is 2.5 ꢀ A. For an NCP562 or
NCP563 (3.0 V), the maximum input voltage will then be
6.0 V.
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.
