Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per standard Torex packaging conventions. Confirm the package type matches the design requirement for thermal dissipation in the target application. Ensure the fixed 0.9V output aligns with the system's power rail requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 0.9V rail is required from a single-cell lithium battery or similar 2V-6V source. The 50mA output limit suits low-power microcontrollers and sensors. Consider the 6-USPEL package for size constraints. Verify that the external inductor and capacitor values meet the stability requirements specified in the official datasheet for the 0.9V configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9272 series of ultra-low quiescent current synchronous buck converters. The series is characterized by high efficiency and small external components.
