Sample circuit configuration 1
R1163xxx1B is a series regulator with the reverse current protection circuit. The CE pin should be pull-up to
system power supply voltage, and ECO pin should be connect to system power supply or VSS. Please select
VOUT voltage equal to the CPU power supply voltage that interfaces to R2023K/T and SRAM.
