Overview
The R1800K009A-TR is a switching voltage regulator from the Nisshinbo Micro Devices R1800K series, designed as an ultra-low power consumption step-down DC/DC converter for energy harvesting applications. It operates with a buck topology and accepts an input voltage range of 2 V to 5.5 V. The device provides a fixed output voltage of 3.3 V and supports an output current of 1 mA. It features a low quiescent current of 144 nA and is housed in a DFN-2730-12 package.
Feature Summary
- Ultra-low quiescent current design optimized for energy harvesting systems
- Buck DC/DC converter topology for efficient step-down regulation
- Fixed 3.3 V output voltage capability
Applications
- Energy harvesting circuits
- Low-power battery-powered devices
- IoT sensor nodes
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure compatibility with your PCB footprint for the DFN-2730-12 package.
Selection Notes
Select this component when designing energy harvesting systems requiring minimal standby power consumption. The fixed 3.3 V output simplifies design for compatible loads. Consider the 144 nA quiescent current for applications where background power drain is critical. Verify input voltage stability within the 2 V to 5.5 V range for optimal performance.
Part Context
This part belongs to the R1800K series of switching regulators from Nisshinbo Micro Devices. The series focuses on ultra-low power step-down converters intended for energy harvesting. Other variants in the series offer different fixed output voltages while maintaining similar low quiescent current characteristics and compact packaging.
Replacement Considerations
Check the R1800K008A-TR and R1800K014A-TR datasheets for alternative fixed output voltages within the same series. These parts share similar electrical characteristics and packaging but differ in regulated output levels.
