Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number XC9286B1ECMR-G against official Torex Semiconductor documentation to confirm the fixed 1.45 V output voltage and SOT-25-5 packaging. Ensure compatibility with system input voltage requirements within the 2.5 V to 5.5 V range. Check RoHS compliance status through manufacturer datasheets before integration into final products.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.45 V output is required from a 2.5 V to 5.5 V input source. The 1.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 15 uA quiescent current for battery life optimization in standby modes. Verify thermal performance within the -40°C to +105°C operating range for the specific application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9286 series of HiSAT-COT synchronous buck converters. The series offers various fixed output voltages while maintaining consistent electrical characteristics such as 1 A output current and 1.2 MHz switching frequency. The 'B1' designation typically indicates specific output voltage coding within the family structure.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Other XC9286 variants with different output voltages (e.g., XC9286B1DCMR-G for 1.35 V) share similar electrical parameters but provide different fixed outputs. Direct pin-compatible replacements require matching the 1.45 V output specification exactly.
