Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number against official Torex Semiconductor documentation to ensure compatibility with your design requirements. Confirm that the SOT-25-5 package dimensions align with your PCB footprint specifications. Ensure that the thermal performance meets your application's operating temperature range of -40°C to +85°C. Cross-reference the datasheet for any specific handling or storage conditions required for this surface-mount device.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a single-cell lithium-ion battery or similar low-voltage source. The 3 MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the 500 mA output limit and the 650 mV minimum input voltage to ensure it fits your system's power budget and input constraints.
