Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the ordering suffix U3T1G corresponds to the SOT-89-3 tape packaging format. Confirm environmental compliance requirements, specifically checking if the G suffix meets specific lead-free or halogen-free standards compared to the standard U suffix. Ensure the selected part number matches the required 1.7 V output specification within the S-1206 series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.7 V rail is required with minimal quiescent current draw. The SOT-89-3 package offers higher thermal dissipation capabilities than smaller packages, supporting the full 250 mA output current rating. Verify that the application load does not exceed the package's power dissipation limits under maximum ambient temperature conditions.
