• Wearable technology systems with strict size limitations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DMR against the official Torex datasheet to confirm the SOT-25-5 package and reel packaging type. Ensure the fixed 3.8 V output aligns with system requirements, as this variant does not support adjustable outputs. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest product documentation before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.8 V output is required from inputs as low as 0.65 V. The 3 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 26 uA quiescent current for battery life optimization in standby modes. Verify that the 0.8 A peak current capability meets the transient load demands of the target application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9142 series of synchronous step-up DC/DC converters manufactured by Torex Semiconductor.
