R1517x Series 500 mA 36V Input Low Supply Current LDO NO. EA−304−201125 OUTLINE R1517x is a CMOS-based LDO that specifically designed 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 105°C 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/C/D and is set to 120 µs (Typ). And the soft-start time in R1517xxxxE/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.

EA−304−201125 TECHNICAL NOTES Phase Compensation In LDO regulators, phase compensation is provided to secure stable operation even when the load current is varied. For this purpose, use the capacitor C2 of 0.1 µF or more (R1517xxxxB/D/E/F) / 1.0 µF or more (R1517x001C). When using a tantalum type capacitor and the ESR (Equivalent Series Resistance) value is large, the output might be unstable. Evaluate the circuit including consideration of frequency characteristics. For the externally adjustable output voltage type (R1517x001C), use 10 kΩ or lower resistance R2. PCB Layout Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable operation may result. Connect 0.1 µF or more of the capacitor C1 between the VDD and GND, and as close as possible to the pins. In addition, connect the capacitor C2 between VOUT and GND, and as close as possible to the pins. 12 R1517x NO. EA−304−201125 OPERATION DESCRIPTION Thermal Shutdown Function Thermal shutdown function is included in this device. 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 (R1517x001C) The output voltage of R1517x001C 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 GND VOUT IIC R2 I2 VFB Output Voltage Adjustment Using External Divider Resistors (R1, R2) RIC of the R1517x001C is approximately Typ. 1.35 MΩ (Ta=25°C, guaranteed by design engineering). For better accuracy, setting R1
