Finding sources (scholarly articles, research books, dissertations) for your literature review is part of the research process, a process that is iterative--you go back and forth along the process as new information is gather and analyze until all necessary data is acquire and you are ready to write. The main steps in this research process are:
Planning: Before searching for articles or books, brainstorm to develop keywords that better describe your research question.
Searching: While searching take note of what other keywords are used to describe your topic and use them to do more searches
♠ Most articles include a keyword section
♠ Key concepts may change name through time so make sure to check for variations
Organizing: Start organizing your results by categories/key concepts or any organizing principle that make sense for you. This will help you later when you are ready to analyze your findings
Analyzing: While reading, start making notes of key concepts and commonalities and disagreement among the research articles you find.
♠ Create a spreadsheet document to record what articles you are finding useful and why.
♠ Create fields to write summaries of articles or quotes for future citing and paraphrasing.
Writing: Synthesize your findings. Use your own voice to explain to your readers what you learn about the literature your search; its weaknesses and strengths; what is missing or ignore
Repeat: at any given time of the process you can go back to a previous step as necessary
All databases have Help pages that explain the best way to search their product. When doing literature reviews, you want to take advantange of all these features since it will facilitate not only finding the articles that you really need but also control how many results and how relevants they are for your search.

There is no magic number regarding how many sources you are going to need for your literature review, it all depends on the topic and what type of the literature review you are doing:
► Are you working on an emerging topic? You are not likely to find many sources, which is good because you are trying to prove that this is a topic that needs more research. But, it is not enough to say that you found few or no articles on your topic in your field. You need to look broadly to other disciplines (also known as triangulation) to see if your research topic has been studied from other perspectives as a way to validate the uniqueness of your research question.
► Are you working on something that has been studied extensively? Then you are going to find many sources and you will want to limit how far you want to look back. Use limiters to eliminate research that may be dated and opt to search for resources published within the last 5-10 years.
