150 mA CMOS Low Iq
Low-Dropout Voltage
Regulator
The NCP551 series of fixed output low dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. The NCP551
series features an ultralow quiescent current of 4.0 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.
The NCP551 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 mF. The
device is housed in the TSOP5 surface mount package. Standard
voltage versions are 1.4, 1.5, 1.8, 2.5, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3,
and 5.0 V. Other voltages are available in 100 mV steps.

DEFINITIONS
Load Regulation
The change in output voltage for a change in output
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 3% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
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.
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 technique such that the average
chip temperature is not significantly affected.
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 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 NCP551 series is
shown in Figure 20.
Input Decoupling (C1)
A 0.1 mF capacitor either ceramic or tantalum is
recommended and should be connected close to the NCP551
package. Higher values and lower ESR will improve the
overall line transient response.
Output Decoupling (C2)
The NCP551 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 mW up to 3.0 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.
Enable Operation
The enable pin will turn on or off the regulator. 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.
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.
Thermal
As power across the NCP551 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 NCP551 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:
PD +TJ(max) *TA
RqJA
If junction temperature is not allowed above the
maximum 125°C, then the NCP551 can dissipate up to
400 mW @ 25°C.
The power dissipated by the NCP551 can be calculated
from the following equation:
Ptot +ƪVin *I
gnd (Iout)ƫ)[Vin *Vout]*I
out
or
VinMAX +Ptot )Vout *Iout
IGND )Iout
If a 150 mA output current is needed then the ground
current from the data sheet is 4.0 mA. For an
NCP551SN30T1 (3.0 V), the maximum input voltage will
then be 5.6 V.

Figure 24. Input Voltages Greater than 12 V
The NCP551 series can be current boosted with a PNP transist-
or. Resistor R in conjunction with VBE of the PNP determines
when the pass transistor begins conducting; this circuit is not
short circuit proof. Input/Output differential voltage minimum is
increased by VBE of the pass resistor.
Short circuit current limit is essentially set by the VBE of Q2 and
R1. ISC = ((VBEQ2 ib * R2) / R1) + IO(max) Regulator
If a delayed turnon is needed during power up of several
voltages then the above schematic can be used. Resistor R,
and capacitor C, will delay the turnon of the bottom regulator.
A regulated output can be achieved with input voltages that
exceed the 12 V maximum rating of the NCP551 series with
the addition of a simple preregulator circuit. Care must be
taken to prevent Q1 from overheating when the regulated
output (Vout) is shorted to GND.
