R1517x Series 500 mA 36V Input Low Supply Current LDO NO. EA-304-170112 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 -40C to 105C 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 adjustable output voltage setting type, which is controlled by external resistances, of R1517x001C. As for the soft-start time, R1517x is fixed internal in R1517xxxxB/C/D and is set to 120 s (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-304-170112 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 F or more (R1517xxxxB/D/E/F) / 1.0 F 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 k 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 F 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-304-170112 OPERATION DESCRIPTION Thermal Shutdown Function Thermal shutdown function is included in this device. If the junction temperature is more than or equal to 160C (Typ.), the operation of the regulator would stop. After that, when the junction temperature is less than or equal to 135C (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 12.0 V VFB = 2.5 V VOUT R1 I1 VFB RIC VOUT IIC R2 I2 VFB GND Output Voltage Adjustment Using External Divider Resistors (R1, R2) RIC of the R1517x001C is approximately Typ. 1.35 M (Ta=25C, guaranteed by design engineering). For better accuracy, setting R1 << RIC reduces errors. The resistance value for R2 should be set to 10 k or lower. It is easily affected by noises when setting the value of R1 and R2 larger, which makes the impedance of VFB pin larger. RIC could be affected by the temperature, therefore evaluate the circuit taking the actual conditions of use into account when deciding the resistance values for R1 and R2. 13 R1517x NO. EA-304-170112 Soft-start Function R1517x is equipped with a constant slope circuit, which achieves a soft-start function. This circuit allows the output voltage to start up gradually when the CE is turned on. The constant slope circuit minimizes the inrush current at the start-up and also prevents the overshoot of the output voltage. For R1517xxxxB/C/D, the capacitor to create the start-up slope is built in this device that does not require any external components. The start-up time and the start-up slope angle are fixed inside the device. In R1517xxxxE/F, the soft-start time is adjustable by inserting the external capacitor to DELAY pin. By using the following equation, the relation between the soft-start time tD [s] and DELAY pin capacitor CD [F] is determined. tD = ((CD + 90 x 10-12) / IDELAY) x 0.73 When the capacitor CD is not used in R1517xxxxE/F, use the DELAY pin as OPEN. At that time, CD = 0 in the above equation, therefore the start-up time is about 26 s. However, be sure to consider approximately 50 s of CE delay time.

The products listed in this document are intended and designed for use as general electronic components in standard applications (office equipment, telecommunication equipment, measuring instruments, consumer electronic products, amusement equipment etc.). Those customers intending to use a product in an application requiring extreme quality and reliability, for example, in a highly specific application where the failure or misoperation of the product could result in human injury or death (aircraft, spacevehicle, nuclear reactor control system, traffic control system, automotive and transportation equipment, combustion equipment, safety devices, life support system etc.) should first contact us. 6. We are making our continuous effort to improve the quality and reliability of our products, but semiconductor products are likely to fail with certain probability. In order to prevent any injury to persons or damages to property resulting from such failure, customers should be careful enough to incorporate safety measures in their design, such as redundancy feature, fire containment feature and fail-safe feature. We do not assume any liability or responsibility for any loss or damage arising from misuse or inappropriate use of the products. 7. Anti-radiation design is not implemented in the products described in this document. 8. The X-ray exposure can influence functions and characteristics of the products. Confirm the product functions and characteristics in the evaluation stage. 9. WLCSP products should be used in light shielded environments. The light exposure can influence functions and characteristics of the products under operation or storage. 10. There can be variation in the marking when different AOI (Automated Optical Inspection) equipment is used. In the case of recognizing the marking characteristic with AOI, please contact Ricoh sales or our distributor before attempting to use AOI. 11. Please contact Ricoh sales representatives should you have any questions or comments concerning the products or the technical information.
