R1500x SERIES
500mA LDO REGULATOR (Operating Voltage up to 24V)
NO.EA-151-130416
OUTLINE
The R1500x series are CMOS-based positive voltage regulator (VR) ICs. The R1500xxxxB has features of high
input voltage operating, 500mA output current drive, and low supply current.
A DMOS transistor is used for the driver, high voltage operating and low on resistance (0.6Ω at VOUT=10V)
device is realized. A standard regulator circuit with a current limit circuit and a thermal shutdown circuit are built
in the R1500x series.
As the operating temperature range is from -40°C to 105°C and maximum input voltage is up to 24V, the
R1500x series are suitable for the constant voltage source for car accessories.
The regulator output voltage is fixed in the R1500x. Output voltage accuracy is ±2.0% and output voltage range
is from 3.0V to 12.0V with a step of 0.1V. The chip enable pin realizes ultra low supply current standby mode.
Since the packages for these ICs are the SOT-89-5 for high density mounting of the ICs on boards, and the
TO-252-5-P2(Non-promotion).
∗) The DMOS (Double Diffused MOS) transistor adopted by R1500x is characterized by a double diffusion structure which
comprises a low density n-type (channel) diffused layer and a high density p-type (sources) diffused layer from the edge
of the gate electrode. The R1500x series possess outstanding properties of high operating voltage and low on-resistance,
which have been achieved by the channel length scaled down to submicron dimensions and decreased thickness of the
gate oxide film.

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 a capacitor C2 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.
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 0.47μF 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.
No.2 pin and No.3 pin of SOT-89-5 and TO-252-5-P2 package must be wired to the GND plane when it is
mounted on board.
Thermal Shutdown
There is the built-in thermal-shutdown function in R1500x series. It discontinues operation of the IC when the
junction temperature becomes over 160°C (Typ.) and IC re-operates when the junction temperature under 135°C.
If the temperature increasing keeps the IC repeats ON and OFF operating. The output becomes the pulse
condition.

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.)
