Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' against official Torex documentation, as standard XC9237 series listings often utilize 'A' or 'B' designators. Confirm package type matches SOT-25-5 requirements. Ensure compatibility with 1.2 MHz switching frequency constraints in your PCB layout. Cross-reference datasheet electrical characteristics for the exact 3.1 V output tolerance before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.1 V output is required from a 2 V to 6 V input source. The 600 mA current capability suits moderate load applications. The 15 uA quiescent current aids battery life extension. Verify that the SOT-25-5 footprint fits the design constraints. Consider thermal performance under full load conditions given the small package size.
