Linear Regulators (LDO) | NCP4523

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.
