RP101x SERIES
0.6% ACCURACY LOW NOISE 300mA LDO REGULATOR
NO.EA-167-111020

OUTLINE
The RP101x 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 RP101x Series are excellent, thus these ICs are very suitable for the power supply for
hand-held communi cation equipment.
The output voltage of these ICs is fixed with high accuracy. Since the p ackages for these ICs are SOT-23-5 and
DFN(PLP)1612-4 (t=0.6mm type) or DFN(PLP)1612-4B (t=0.4mm type), therefore high density mounting of the
ICs on boards is possible.

∗) The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25V. In case of exceeding this
specification, the IC must be operated on condition that the Input Voltage is u p to 5.5V and the total operating
time is within 500hrs.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment sho uld b e 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 su rge. And the semicondu ctor devices may receive seriou s damage when they continu e
to operate over the recommended operating conditions.

TECHNICAL NOTES
When using these ICs, consider the following p oints:
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a capacitor C2 with 1.0μF or more capacity.
Ceramic capacitors have different temperature characteristics and bias characteristics depending on their
dimensions and manufacturers. If the setting voltage is 2.5V or more and the capacitor’s dimensions for VOUT
equal to 1.0mm by 0.5mm or smaller than that, the capacitance value might be extremely low. As a result, the
capacitance might be much less than expected. In such cases, the operation might be unstable at low
temperature. (−20°C or less) In that case, use a larger capacity, or a large dimensions’ capacitor. (For example
1.6mm by 0.8mm)
If a tantalum capacitor is selected as an output capacitor, large ESR may be a cause of unstable operation.
Evaluate the operation of PCB with considerable frequency characteristics.
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor C1 with a capacitance value as much as 1.0μF or more between VDD and GND pin, and as
close as possible to the pins.
Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring
as short as possible.

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