R1518x Series 1 A 36V Input Low Supply Current LDO NO.EA−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 105°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). R1518xxxxE/F can adjust the soft-start time with an external capacitor. R1518x is available in two packages for ultra high wattage: HSOP-6J and TO-252-5-P2.

If the junction temperature is more than or equal to 160°C (Typ.), the operation of the regulator would stop. After that, when the junction temperature is less than or equal to 135°C (Typ.), the operation of the regulator would restart. Unless the cause of rising temperature is removed, the regulator repeats on and off, and output waveform would be like consecutive pulses. Adjustable Output Voltage Setting (R1518x001C) The output voltage of R1518x001C can be adjusted by using the external divider resistors (R1, R2). By using the following equation, the output voltage (VOUT) can be determined. The voltage which is fixed inside the IC is described as VFB. VOUT = VFB x ((R1 + R2) / R2) Recommended Range: 2.5 V ≤ VOUT ≤ 20.0 V VFB = 2.5 V VOUT R1 I1 VFB RIC VOUT IIC R2 I2 GND VFB Output Voltage Adjustment Using External Divider Resistors (R1, R2) RIC of the R1518x001C is approximately Typ. 1.35 MΩ (Ta=25C, guaranteed by design engineering).
