Special Purpose Regulators Procurement Notes

Verify the specific package variant required, as the ET631xx series is available in DFN4 (1x1) or SOT23-5 configurations. Confirm that the fixed 1.50V output matches the system design requirements, as other variants in the series offer different voltage steps. Ensure compliance with RoHS and halogen-free standards if specified for the target assembly process. Check the manufacturer's latest datasheet for any updates on pinout or electrical characteristics before finalizing procurement.

Special Purpose Regulators Selection Notes

Select this component when ultra-low standby current is critical for battery-operated systems. The 150mA load capability supports moderate power demands while maintaining efficiency. Consider the dynamic quiescent current adjustment feature for applications with varying load conditions. Verify that the input voltage range of 2.2V to 5.5V aligns with the source supply. The fixed 1.50V output eliminates the need for external resistors for voltage setting, simplifying the circuit design.
