The R1131N181A-TR-FE is a low voltage linear regulator from the R1131x series, designed to provide a fixed output voltage of 1.8V with a maximum output current of 300mA. It operates within an input voltage range of 1.4V to 6.0V and features a low supply current of approximately 80OºA for output voltages below 1.8V and 60OºA for higher voltages. The device includes a current limit circuit to prevent damage from overcurrent conditions and has a typical dropout voltage of 0.48V at 1.0V output, 0.31V at 1.5V output, and 0.23V at 3.0V output. The R1131N181A-TR-FE also offers a standby mode with a consumption current of only 0.1OºA, making it suitable for battery-powered applications. It has a ripple rejection of 65dB at 1kHz and an output voltage accuracy of ±2.0%. The device is packaged in a compact SOT-23-5 format, allowing for high-density mounting on PCBs. It is suitable for use in precision voltage references and as a power source for various electronic devices, including cameras and handheld communication equipment.
