R1514x Series
AEC-Q100 Grade2 Certified
150 mA Voltage Regulator (Wide Input Voltage Range) for Automotive Applications
NO. EC-152-140220
OUTLINE
The R1514x is a CMOS-based positive voltage regulator (VR) IC featuring 150 mA output current. It is
specifically designed for automotive applications. The R1514xxxxB has features of high input voltage and
ultra-low supply current. A peak current limit circuit, a short current limit circuit, and a thermal shutdown circuit
are built in the R1514x.
The operating temperature is
−40°C
to 105°C and the maximum input voltage is 36 V, the R1514x is very
suitable for power source of car accessories.
The regulator output voltage is fixed in the R1514xxxxB and can be selected with a step of 0.1 V in the range
of 2.0 V to 12.0 V. The Output voltage accuracy is ±2%.
The packages for this IC are the SOT-89-5 for space saving and the HSOP-6J for higher power applications.

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.

All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended operating
ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the semiconductor
devices may receive serious damage when they continue to operate over the recommended operating ratings.
