LDL1117S50R-JSM

The LDL1117S is a series of low-dropout three-terminal voltage regulators with a 1.5V dropout voltage at 1A output current. The LDL1117S series provides current limiting and thermal shutdown. The circuit incorporates an advanced bandgap reference to ensure output voltage accuracy within 1% for the 3.3V, 5.0V, and adjustable versions, and within 2% for the 1.2V version. Current limiting ensures the specified output current and controlled short-circuit current. On-chip thermal shutdown prevents excessive junction temperature resulting from any combination of overload and ambient temperature. The LDL1117S has an adjustable version that provides output voltages from 1.25V to 12V using only two external resistors. The LDL1117S series is available in the industry-standard SOT-223 3-lead power package.
