R5325x SERIES
Non-promotion
150mA Dual LDO REGULATOR
NO.EA-127-130501
OUTLINE
The R5325x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current (Typ. 3.0μA), low dropout, and fast transient response. Each of these voltage regulator ICs consists of a
voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip
enable circuit.
These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable
function prolongs the battery life of each system. The line transient response and load transient response of the
R5325x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication
equipment.
The supply current at no load of R5325x Series is remarkably reduced compared with R5323x Series. The
mode change signal to reduce the supply current is not necessary.
The output voltage of these ICs is internally fixed with high accuracy (±1.0%). Since the packages for these
ICs are SOT-23-6 and DFN(PLP)1820-6 package, dual LDO regulators are included in each, 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.
