Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B' indicates the correct output voltage variant, as other letters denote different voltages. Confirm the 'G' suffix aligns with RoHS compliance requirements. Ensure the SOT-25-5 package footprint matches the design layout. Cross-reference the datasheet for thermal performance under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V output is required from a 2 V to 6 V source. The 600 mA current capability suits moderate load applications. The 3 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the absence of a shutdown feature meets system control needs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9236 series of synchronous step-down converters. The series includes variants with different fixed output voltages, distinguished by letter codes such as A, B, and C.
