NCP562, NCP563
80 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. This series
features an ultra−low quiescent current of 2.5
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 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
mF.
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.
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.
Maximum Power Dissipation
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
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.
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.
