OUTLINE
The R5324D Series are CMOS-based multi positive voltage regulator ICs with high output voltage accuracy, low supply current, low noise, low dropout and high ripple rejection. The R5324D Series contain three voltage regulators. Each of these voltage regulators in the R5324D Series consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on.
The chip enable function contributes to prolong battery life. Further, regulators in the R5324D Series are with low dropout voltage, excellent load transient response and line transient response, thus the R5324D series are very suitable for the power supply for hand-held communication equipment.
Since the package for these ICs is SON-8, high density mounting of the ICs on boards is possible.
