R1517x Series
AEC-Q100 Grade 1 Compliant
500 mA 36V Input Low Supply Current LDO for Automotive Applications
OUTLINE
NO. EC－304－141222
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.
