R1517S

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-...
