3-MODE 150mA LDO REGULATOR
OUTLINE
NO.EA-110-130415
The R1162x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy and low
supply current. 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 so on. The output voltage is internally fixed with
high accuracy.
These ICs perform with the chip enable function and realize a standby mode with ultra low supply current. To
prevent the destruction by over current, the current limit circuit is included. The R1162x Series have 3-mode.
One is standby mode with CE or standby control pin. Other two modes are realized with ECO pin. Fast Transient
Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin. Consumption current is reduced
at Low Power Mode compared with Fast Transient Mode. The output voltage is maintained between FT mode
and LP mode.
Since the packages for these ICs are SOT-23-5 and SON1612-6 packages, 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.

When using these ICs, consider the following points:
1.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 as much as 1.0μF capacitor between VDD and GND pin as close as possible.
Set external components, especially the output capacitor as close as possible to the ICs and make wiring as
short as possible.
2.Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, be sure to use a 0.47μF or more capacitor COUT with good frequency characteristics and ESR
(Equivalent Series Resistance).
If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable.
Evaluate your circuit with considering frequency characteristics.
Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature
characteristics are different. Evaluate the circuit with actual using capacitors.

ESR vs. Output Current
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied.
For this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent
Series Resistance) in the range described as follows:
The relations between IOUT (Output Current) and ESR of 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.

5.The products listed in this document are intended and designed for use as general electronic
components in standard applications (office equipment, telecommunication equipment,
measuring instruments, consumer electronic products, amusement equipment etc.). Those
customers intending to use a product in an application requiring extreme quality and reliability,
for example, in a highly specific application where the failure or misoperation of the product
could result in human injury or death (aircraft, spacevehicle, nuclear reactor control system,
traffic control system, automotive and transportation equipment, combustion equipment, safety
devices, life support system etc.) should first contact us.
6.We are making our continuous effort to improve the quality and reliability of our products, but
semiconductor products are likely to fail with certain probability. In order to prevent any injury to
persons or damages to property resulting from such failure, customers should be careful enough
to incorporate safety measures in their design, such as redundancy feature, firecontainment
feature and fail-safe feature. We do not assume any liability or responsibility for any loss or
damage arising from misuse or inappropriate use of the products.
7.Anti-radiation design is not implemented in the products described in this document.
8.Please contact Ricoh sales representatives should you have any questions or comments
concerning the products or the technical information.
For the conservation of the global environment, Ricoh is advancing the decrease of the negative environmental impact material.
After Apr. 1, 2006, we will ship out the lead free products only. Thus, all products that will be shipped from now on comply with RoHS Directive.
Basically after Apr. 1, 2012, we will ship out the Power Management ICs of the Halogen Free products only. (Ricoh Halogen Free products are
also Antimony Free.)
