Overview: R1518x Series
AEC-Q100 Compliant 1 A 36V Input Low Supply Current LDO for Automotive Applications
NO.EC-329-230124
OUTLINE
R1518x is a CMOS-based LDO that specifically designed for automotive applications featuring 1 A output current and 36 V input voltage. In addition to a conventional regulator circuit, R1518x 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 R1518x is very suitable for power source of car accessories.
R1518x is available in R1518xxxxB/D/E/F with the internally fixed output voltage, and R1518xxxxD/F with the auto-discharge function at standby.
The output voltage of R1518x001C can be set with an external resistor, and the setting range is from 2.5V to Max 20V. R1518xxxxB/C/D internally fixes the soft-start time at 120 µs (Typ). R1518Jxx1E/F can adjust the softstart time with an external capacitor.
R1518x is available in two packages for ultra high wattage: HSOP-6J and TO-252-5-P2.
