NCP5426
LDO Regulator/Vibration
Motor Driver
The NCP5426 series of fixed output, 150 mA low dropout linear
regulators are designed to be an economical solution for a variety of
applications. Each device contains a voltage reference unit, an error
amplifier, a PNP power transistor, resistors for setting output voltage,
an under voltage lockout on the input, an enable pin, and current limit
and temperature limit protection circuits.
The NCP5426 is designed for driving a vibration motor using
ceramic capacitors on the output. The device is housed in the
micro−miniature TSOP−5 surface mount package. The NCP5426 is
available in output voltages of 1.2 V to 2.0 V in 0.1 V increments.

DEFINITIONS
Load Regulation
The change in output voltage for a change in output load
current at a constant temperature and input voltage.
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 2.0% below
its nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Output Noise Voltage
This is the integrated value of the output noise over a
specified frequency range. Input voltage and output load
current are kept constant during the measurement. Results
are expressed in mVRMS or nV √Hz.
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 150°C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.
Quiescent Current
The current which flows through the ground pin when the
regulator 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 power dissipation level at which the junction
temperature reaches its maximum operating value, i.e.
125°C.
