R5326x SERIES
Automatic Mode Shift Dual 150mA LDO
NO.EA-138-130501
OUTLINE
The R5326x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, Typ. 5.5μA low
supply current, and remarkably improved transient response compared with the conventional low supply current
voltage regulators. The supply current of IC itself is automatically shifts between fast mode and low power mode
depending on the load current. (The current threshold is fixed internally.) Each of these voltage regulator ICs
consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, a current limit
circuit for preventing from the destruction by an over current, and so on.
The chip enable function realizes the standby mode with ultra low supply current.
Since the packages for these ICs are SOT-23-6 (Non-promotion) and DFN(PLP)1820-6, and chip size
package, WLCSP-6-P1 (Non-promotion), dual LDO regulators are included in each package, 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.
