Richtek offers diverse DDR memory power solutions including linear DDR terminators and PMICs. The linear DDR terminators have both source and sink functionality and require very tight output voltage regulation. These parts can be used with many types of DDR memory from DDR1 to DDR5 as well as Low Power (LP) DDR3/4/5. The low Vin LDOs require an external low power bias voltage. Selecting a suitable product for your applications should be based on the DDR type, current rating and features such as output voltage sensing, REFOUT and different power state settings via S3 / S5 pins.
