RP118K Description

Short technical summary and product information.

The RP118K series voltage regulator from Nisshinbo Micro Devices is engineered for applications requiring extended battery life and miniaturization, such as wearable equipment and IoT devices. It boasts an ultra-low supply current of typically 0.2 µA, contributing to long service life and smaller battery footprints.

Key electrical specifications include an output voltage accuracy of ±0.8%, an input voltage range of 1.7 V to 5.5 V, and a selectable output voltage range from 1.2 V to 3.6 V in 0.1 V steps. The device also features a built-in fold-back protection circuit with a typical current of 50 mA in short mode and a low dropout voltage of 0.1 V at 100 mA output current.

The RP118K operates in an automatic mode, seamlessly shifting between fast response and low power modes. It is recommended to use ceramic capacitors of 1.0 µF or more for stability. The regulator is available in compact packages, including the DFN(PL)1010-4B, enabling minimal footprint solutions on space-constrained boards.

Typical applications include wearable devices like smartwatches and smart bands, Li-ion battery-powered equipment, coin cell-powered devices, and low-power RF modules such as Bluetooth Low Energy, Zigbee, and ANT. It is also suitable for low-power CPUs, memory, sensor devices, and energy harvesting systems.
