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 V
OUT
=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.
