Nisshinbo Micro Devices Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators RP130N291D-TR-FE

The RP130N291D-TR-FE is a low noise linear voltage regulator IC designed for applications requiring high output voltage accuracy and low dropout voltage. It operates within an input voltage range of 1.7 V to 6.5 V and provides a fixed output voltage range from 1.2 V to 5.3 V with a typical output voltage accuracy of ±1.0%. The device features a low supply current of approximately 38 µA and a standby current of 0.1 µA, which is beneficial for battery-powered applications. The RP130N291D-TR-FE includes built-in protection features such as a fold-back current limit circuit and improved transient response characteristics compared to conventional products. It is available in a compact SOT-23-5 package, allowing for high-density mounting on circuit boards. The recommended output capacitor is a ceramic type of 0.47 µF or more, ensuring stable operation. This regulator is suitable for powering portable communication devices, cameras, and other electronic appliances requiring a stable voltage supply.
