R5324x SERIES
Limited
TRIPLE LDO
NO. EA-099-120404
OUTLINE
The R5324x 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 R5324x Series contain three voltage
regulators. Each of these voltage regulators in the R5324x 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 R5324x Series are with
low dropout voltage, excellent load transient response and line transient response, thus the R5324x series are
very suitable for the power supply for hand-held communication equipment.
Since the packages for these ICs are SON-8 and DFN(PLP)2527-10, high density mounting of the ICs on
boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommended operating conditions.
