NCP4523

CMOS 3CH−LDOs

for RF Unit

The NCP4523 Series are multi voltage regulator ICs with high

output voltage accuracy, extremely low supply current, low noise, low

ON−resistance 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 hand−held

communication equipment.

The output voltage of each regulator is fixed with high accuracy by

laser trim.

Since the package for these ICs is SSOP−8, high density mounting

of the ICs on boards is possible.
