FSP1117KE

1A LOW DROPOUT LINEAR REGULATOR FSP1117 FEATURES Low Dropout Voltage: 1.15V at 1A Output Current Trimmed Current Limit On-chip Thermal Shutdown Three-terminal Adjustable or Fixed 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V GENERAL DESCRIPTION The FSP1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The FSP1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 3.3.V, 5.0V and adjustable versions or 2% for 1.2V version. 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 FSP1117 has an adjustable version that can provide the output voltage from 1.25V to 12V with only two external resistors. The FSP1117 series is available in the industry standard TO220-3L, TO263-3L, TO252-2L and SOT223 power packages.
