Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TR-FE' corresponds to the required tape-and-reel packaging configuration and RoHS compliance status as defined by Nisshinbo Micro Devices. Confirm that the fixed 2.7V output voltage aligns with the target circuit requirements, as this parameter cannot be adjusted externally. Ensure compatibility with the SOT-23-5 footprint during PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.7V output is required from a variable input source between 0.6V and 5.5V. The 1A current capability suits moderate load applications. Consider the 1.2MHz switching frequency for minimizing inductor size compared to lower-frequency alternatives. Verify thermal performance within the -40°C to +85°C range for the intended environment.
