Nisshinbo Micro Devices Inc. Voltage Regulators - Linear RP131S101B-E2-FE

The RP131S101B-E2-FE is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output current of 1A. It operates within an input voltage range of 1.6V to 6.5V and offers a minimum output voltage of 0.8V, adjustable in 0.1V steps up to 5.5V. The device features a low dropout voltage of approximately 0.5V at 2.8V output and 1A load, ensuring efficient performance in low-voltage applications. This regulator includes several built-in protection features such as current limit, thermal shutdown, and an inrush current limit circuit. It also supports a standby mode with a typical supply current of 65µA and an ultra-low standby current of 0.15µA. The output voltage accuracy is ±1.0%, with good ripple rejection of 70dB at 1kHz. The RP131S101B-E2-FE is available in multiple package options, including HSOP-6J, making it suitable for high-density mounting on PCBs. It is recommended for use in battery-powered devices, portable communication equipment, and various consumer electronics.
