Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G1B' against official Torex documentation to confirm the fixed output voltage value and tolerance. Ensure the ordering code matches the required switching frequency selection pin configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Cross-reference the package marking code to distinguish from similar series variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.25V output is required within a 1.8V to 6.0V input range. Choose based on the need for manual control over switching modes to balance ripple and efficiency. Consider the 600mA current limit and the benefit of ceramic capacitor compatibility due to internal resistance values. Evaluate the 1.2MHz or 3.0MHz frequency options against inductor size constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series of 600mA driver transistor built-in synchronous step-down DC/DC converters.
