R1517x Series AEC-Q100 Grade 1 Compliant 500 mA 36V Input Low Supply Current LDO for Automotive Applications NO. EC-304-201125 OUTLINE 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 40C to 125C and the maximum input voltage is 36 V, the R1517x is very suitable for power source of car accessories. R1517x supports the internal fixed output voltage type of R1517xxxxB/D/E/F, and the output voltage of R1517x001C can adjust the output voltage be set with an external resistor, and the setting range is from 2.5V to Max 20V. As for the soft-start time, R1517x is fixed internal in R1517xxxxB/D/E/F and is set to 120 s (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.
