The LSP1117 is a series of low dropout three-terminal regulators with a dropout of 1.4V at 1A output current. The LSP1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 2% for 1.2V, 1.5V, 1.8V, 2.5V, 3.3.V, 5.0V and adjustable versions. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.
The LSP1117 has an adjustable version that can provide the output voltage from 1.2V to 12V with only two external resistors. The LSP1117 series is available in the industry standard TO252-3L and SOT223 power packages.
