RP153L SERIES
150mA DUAL LDO REGULATOR WITH 2 INPUT PINS
NO. EA-201-111020
OUTLINE
The RP153L Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current, low dropout, and high ripple rejection. 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 RP153L 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 internally fixed with high accuracy. Since the package for these ICs are
DFN1216-8, dual LDO regulators are included in each package are high density mounting of the ICs on boards
is possible.
In RP153L, the power supply of each circuit can be individually supplied. The transient response
characteristic of D and E Version is improved.

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:
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 (0.22μF or more) for COUT1 and COUT2 with good frequency characteristics and
ESR (Equivalent Series Resistance).
(Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for
phase compensation, the operation might be unstable. Because of this, test these ICs with as same external
components as ones to be used on the PCB.)
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect capacitors with a capacitance value as much as 0.22μF or more between VDD and GND pin, and as
close as possible to the pins (CIN1/CIN2).
Set external components, especially the output capacitors, as close as possible to the ICs, and make wiring
as short as possible (COUT1/ COUT2).

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.
