R5326x SERIES
Automatic Mode Shift Dual 150mA LDO
NO.EA-138-111025
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 (Limited) and DFN(PLP)1820-6, and chip size package,
WLCSP-6-P1, 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.

TECHNICAL NOTES
When using these ICs, consider the following points:
Mounting on PCB
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor with a capacitance value as much as 1.0μF or more as C1 between VDD and GND pin, and
as close as possible to the pins.
Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as
short as possible.
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use capacitors C2 and C3 which are shown below table “Recommended Ceramic capacitor for
output “If you use a tantalum type capacitor and ESR value of the capacitor is Iarge, output might be unstable.
Evaluate your circuit with considering frequency characteristics.

ESR vs. Output Current
When using these ICs, consider the following points:
The relations between IOUT (Output Current) and ESR of an output capacitor are shown below.
The conditions when the white noise level is under 40μV (Avg.) are marked as the hatched area in the graph.
