The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 6 RP112x NO.EA-258-131024 TYPICAL APPLICATIONS VDD C1 RP112x Series CE VOUT VOUT C2 GND External Parts Example: C1, C2: Ceramic Capacitor 1.0F, Murata, GRM155B31A105KE15 TECHNICAL NOTES Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a 1.0F 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 1.0F 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). 7 RP112x NO.EA-258-131024 PACKAGE INFORMATION * Power Dissipation (DFN(PLP)1010-4) Power Dissipation (PD) depends on conditions of mounting on board.
