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

Verify the specific suffix 'FR' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Torex Semiconductor Ltd specifications. Ensure compatibility with surface-mount assembly processes given the SOT-223 package type. Cross-reference datasheet revisions to confirm electrical parameter consistency prior to integration into production designs.

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

Select this component when a fixed 3.9V rail is required with moderate current demands up to 400mA. Consider the 2V minimum input voltage for applications utilizing single-cell lithium batteries or similar sources. Evaluate the 8µA standby current against system power budget constraints. Verify that the SOT-223 package fits the available PCB real estate and thermal dissipation requirements for the target enclosure.
