AEC-Q100 Grade 1 Compliant
500 mA 36V Input Low Supply Current LDO for Automotive Applications
OUTLINE
NO. EC304141222
R1517x is a CMOS-based LDO that specifically designed for automotive applications featuring 500 mA output
current and 36 V input voltage. In addition to a conventional regulator circuit, R1517x consists of a constant slope
circuit as a soft-start function, a fold-back protection circuit, a short current limit circuit, and a thermal shutdown
circuit. Besides the low supply current by CMOS, the operating temperature is 40°C to 125°C and the maximum
input voltage is 36 V, the R 1517x is ver y s uit able f or power s our c e of c ar acc es s or ies .
R1517x supports the internal fixed output voltage type of R1517xxxxB/D/E/F and the adjustable output voltage
setting type, which is controlled by external resistances, of R1517J001C. As for the soft-start time, R1517x is
fixed internal in R1517xxxxB/D/E/F and is set to 120 µs (Typ). And the soft-start time in R1517Jxx1E/F is
adjustable by external capacitors. R1517x supports the auto-discharge function at standby in R1517xxxxD/F.
R1517x is available in two packages for ultra-high wattage: HSOP-6J and TO-252-5-P2.

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 CONDITION
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.
