Nisshinbo Micro Devices Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators RP131S401D-E2-FE

The RP131S401D-E2-FE is a linear voltage regulator from the RP131x series, designed to deliver a fixed output voltage with a maximum output current of 1A. It operates within an input voltage range of 1.6V to 6.5V and can provide 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 protective features such as built-in thermal shutdown, current limit circuits, and an inrush current limit circuit. It also supports a chip enable function that allows for ultra-low standby current consumption of 0.15µA, making it suitable for battery-powered devices. The recommended output capacitor values are 2.2µF for output voltages up to 3.6V and 4.7µF for higher voltages, with a preference for ceramic capacitors. The RP131S401D-E2-FE is available in multiple package options, including HSOP-6J, which facilitates high-density mounting on PCBs. This product is suitable for various applications, including portable communication devices, cameras, and notebook PCs, making it a versatile choice for engineers looking for reliable voltage regulation solutions.
