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.
