For this purpose, use a 1.0 F or more capacitor C2. In case of using a tantalum capacitor, the output may be unstable due to inappropriate ESR. Therefore, the full range of operating conditions for the capacitor in the application should be considered. PCB Layout The high impedances of VDD and GND could be a reason for the noise pickup and unstable operation. Therefore, it is imperative that the impedances of VDD and GND be the lowest possible. Also, place a 1.0 F or more capacitor (C1) between VDD pin and GND pin as close as possible to each other. As for C2 output capacitor that is used for phase compensation, place it between VOUT pin and GND as close as possible to each other (Refer to TYPICAL APPLICATIONS). 8 RP112x No. EA-258-180621 TYPICAL

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.
