RP103x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-149-131018
OUTLINE
The RP103x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference
unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load
transient response of the RP103x Series are excellent, thus these ICs are very suitable for the power supply for
hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are
DFN(PLP)1010-4, SC-82AB, SC-88A (Non-promotion), SOT-23-5, therefore 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.

Output voltage accuracy is
±20mV.

Maximum input voltage is 5.25V. If, for any reason the input voltage exceeds 5.25V, it has to be no more than 5.5V,
and total operating time should be within 500 hours.
