NO. EA-345-221111 TYPICAL APPLICATIONS R1511xxxxB VDD CE VOUT GND CIN COUT CIN=Ceramic 1.0μF COUT=Ceramic 6.8μF R1511x001C VDD VFB VOUT GND CIN COUT CIN=Ceramic 1.0μF COUT=Ceramic 6.8μF R2 RFB TECHNICAL NOTES PCB Layout and GND Wiring Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable operation may result. Connect a C IN capacitor with 1.0µF or more value between the V DD and GND pins, and as close as possible to the pins. Likewise, connect a COUT capacitor with suitable values between the VOUT and GND pins, and as close as possible to the pins (refer to the Typical Application above). In the case of using HSOP-6J package, make sure to wire No. 2, No. 3, and No. 5 pins to the GND plane. Also, in the case of using TO-252-5-P2 package, make sure to wire No. 2 and No. 3 pins to the GND plane. Phase Compensation In the R1511x, phase compensation is provided to secure stable operation even when the load current is varied. For this purpose, make sure to use a COUT capacitor. In case of using a tantalum type capacitor and the ESR (Equivalent Series Resistance) value of the capacitor is large, the output might be unstable. Evaluate the circuit including consideration of frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit taking actual characteristics into account.

NO. EA-345-221111 Thermal Shutdown R1511x contains a thermal shutdown circuit, which stops regulator operation if the junction temperature of R1511x becomes higher than 160 ºC (Typ.). Additionally, if the junction temperature after the regulator being stopped decreases to a level below 135 ºC (Typ.), it restarts regulator operation. As a result the operation of the thermal shutdown circuit causes the regulator repeatedly to turn off and on until the causes of overheating are removed. As a consequence a pulse shaped output voltage occurs. Adjustable Output Voltage Setting (R1511x001C) The output voltage of R1511x001C 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: 3.0 V ≤ VOUT ≤ 12.0 V VFB = 3.0 V RFB of the R1511x001C is approximately Min. 1.0 MΩ (guaranteed by design). For better accuracy, setting R1 << RFB reduces errors. The resistance value for R2 should be set to 39 kΩ 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.

Connecting a schottky diode (D1) between the V OUT pin and GND has the effect of preventing damage to them.

However, if there is an agreement on the warranty period in the basic transaction agreement, quality assurance agreement, delivery specifications, etc., it shall be followed. 8-2. Quality Warranty Remedies When it has been proved defective due to manufacturing factors as a result of defect analysis by us, we will either deliver a substitute for the defective product or refund the purchase price of the defective product. Note that such delivery or refund is sole and exclusive remedies to your company for the defective product. 8-3. Remedies after Quality Warranty Period With respect to any defect of this product found after the quality warranty period, the defect will be analyzed by us. On the basis of the defect analysis results, the scope and amounts of damage shall be determined by mutual agreement of both parties. Then we will deal with upper limit in Section 8-2. This provision is not intended to limit any legal rights of your company. 9. Anti-radiation design is not implemented in the products described in this document. 10. The X-ray exposure can influence functions and characteristics of the products. Confirm the product functions and characteristics in the evaluation stage. 11. WLCSP products should be used in light shielded environments. The light exposure can influence functions and characteristics of the products under operation or storage. 12. Warning for handling Gallium and Arsenic (GaAs) products (Applying to GaAs MMIC, Photo Reflector). These products use Gallium (Ga) and Arsenic (As) which are specified as poisonous chemicals by law. For the prevention of a hazard, do not burn, destroy, or process chemically to make them as gas or power. When the product is disposed of, please follow the related regulation and do not mix this with general industrial waste or household waste. 13. Please contact our sales representatives should you have any questions or comments concerning the products or the technical information.
