NCP4523
CMOS 3CHLDOs
for RF Unit
The NCP4523 Series are multi voltage regulator ICs with high
output voltage accuracy, extremely low supply current, low noise, low
ONresistance and high ripple rejection by CMOS process. The
NCP4523 Series contain three voltage regulators. Each of these
voltage regulators in the NCP4523 Series consists of a voltage
reference unit, an error amplifier, resistors for setting output voltage, a
current limit circuit and a chip enable circuit.
The chip enable function contributes to prolong battery life. Further,
regulators in the NCP4523 Series are with low dropout voltage,
excellent load transient response and line transient response, thus the
NCP4523 series are very suitable for the power supply for handheld
communication equipment.
The output voltage of each regulator is fixed with high accuracy by
laser trim.
Since the package for these ICs is SSOP8, high density mounting
of the ICs on boards is possible.
