general description
the ams1117 is a low-dropout linear regulator that operates in the input voltage range from +2.5v to +7.0v and delivers 600ma output current.
the ams1117 is available in two types, fixed output voltage type or adjustable output voltage type. the fixed output voltage type is preset at an internally trimmed voltage 1.8v, 2.5v, or 3.3v. other options 1.5v, 2.85v, 3.0v and 3.6v are available by special order only. the output voltage range of the adjustable type is from 1.25v to 5v.
the ams1117 consists of a 1.25v bandgap reference, an error amplifier, and a p-channel pass transistor. other features include short-circuit protection and thermal shutdown protection. the ams1117 devices are available in sot-223 and to-252 packages.
