Additional Details

The R1114N301D operates within a specified input voltage range. It features a built-in overcurrent protection circuit that limits the output current in case of a short circuit or overload condition. The thermal shutdown protection disables the output when the junction temperature exceeds a certain threshold, preventing damage to the IC. The device is typically available in a small SOT-23 or similar surface-mount package. Detailed specifications, including input voltage range, output current capability, and temperature operating range, can be found in the manufacturer's datasheet.
