Nisshinbo Micro Devices Inc. Voltage Regulators - Linear RP131S521D-E2-FE

The RP131S521D-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 can deliver output voltages from 0.8V to 5.5V in 0.1V increments. The device features a low dropout voltage of approximately 0.5V at 2.8V output and 1A load, ensuring efficient operation in low-voltage applications. This regulator includes several built-in protection features, such as current limit circuits, thermal shutdown, and an inrush current limit circuit. It also supports a standby mode with a typical supply current of 65¬µA and an ultra-low standby current of 0.15¬µA. The output voltage accuracy is ¬±1.0%, with a temperature-drift coefficient of ¬±100ppm/¬8C, making it suitable for precision applications. The RP131S521D-E2-FE is available in a 6-HSOP-J package, which is conducive to high-density mounting on circuit boards. It is recommended for use in battery-powered devices, portable communication equipment, and various consumer electronics.
