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

Verify the specific suffix 'T' indicates the extended operating temperature range up to 105°C compared to standard variants. Confirm the 'PR-G' designation corresponds to the SOT-89-5 package format and RoHS compliance status. Ensure the ordering code matches the required 3.45V fixed output specification before finalizing procurement.

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

Select this variant when an extended industrial temperature range is required alongside the standard LDO performance metrics. The inclusion of the internal discharge switch makes it suitable for applications requiring rapid power-down response times. Verify that the system input voltage remains within the specified 1.6V to 5.5V window to ensure proper regulation.
