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.    FEATURES  Input Voltage Range (Maximum Rating) ················ 3.5 V to 36.0 V (50.0V)  Operating Temperature Range ···························· 40°C to 125°C  Supply Current················································· Typ. 18 µA  Standby Current ··············································· Typ. 0.1 µA  Dropout Voltage ··············································· Typ. 0.35 V (IOUT = 500 mA, VOUT = 5.0 V)  Output Voltage Accuracy ···································· ±0.8% (VOUT ≤ 5.0 V)  Temperature-Drift Coefficient of Output Voltage······· Typ. ±60 ppm/°C (−40°C ≤ Ta ≤ 125°C)  Line Regulation ················································ Typ. 0.01%/V  Packages ······················································· HSOP-6J, TO-252-5-P2  Output Voltage Range ······································· 2.5 V/2.8 V/3.0 V/3.3 V/3.4 V/5.0 V/ 6.0 V/8.0 V /8.5 V/9.0 V * Contact Ricoh sales representatives for other voltages.
