Grant agencies like National Science Foundation (NSF) demands a compulsory data deposit policy. Some funders require data to be deposited in specific data centers like ESRC and NERC. Advice should be sought from funders or grant agencies for the accessibility of datasets to fulfill their specific requirement.
When you choose an appropriate data repository, you may consider whether your publishers and collaborators have any requirements for data deposit. For example SpringerNature's Data Policies require authors to submit datasets to the recommended subject repositories.
Mendeley Data is the University of Manchester's recommended general-purpose research data repository where no discipline-specific solution is available. Figshare is a general-purpose data repository which allow researchers to freely deposit up to 20 GB (single file size limit of 5 GB) of data and request a DOI for citing the dataset. Zenodo is another choice of general-purpose data repository.
