Additional Details

The RP100N181D-TR-F operates with an input voltage range typically from 1.7V to 5.5V, delivering a fixed output voltage of 1.8V with a high degree of accuracy. It features a built-in overcurrent protection circuit that limits the output current in the event of a short circuit or overload, preventing damage to the regulator and the connected load. The thermal shutdown protection feature disables the output when the junction temperature exceeds a certain threshold, protecting the regulator from overheating. The device is available in a compact DFN(PLP) package, making it ideal for applications where board space is limited. The low dropout voltage characteristic enables the regulator to operate efficiently even when the input voltage is close to the output voltage, maximizing battery life in portable applications.
