General Description

The HPL5331 linear regulator is designed to provide a regulated voltage with bi-directional output current for DDR-SDRAM termination. The HPL5331 integrates two power transistors to source or sink current up to 3A. It also incorporate current-limit, thermal shutdown and shutdown control functions into a single chip. Current-limit circuit limits the short-circuit current.
