Frequently Asked Questions

What is the dropout voltage of TLV1117LV28DCYR at full load, and why does it matter for 3.3 V input systems?

TLV1117LV28DCYR has a maximum dropout voltage of 0.8 V and a nominal dropout of 0.57 V at rated load. With a 3.3 V input, this allows stable 2.8 V output with a 0.5 V margin, supporting image sensors, RF modules, and microcontroller I/O that require a regulated 2.8 V rail.

How much output current can TLV1117LV28DCYR supply, and which loads does its SOT-223 package handle thermally?

TLV1117LV28DCYR delivers up to 800 mA continuous output current. The SOT-223 3-pin package includes a large thermal pad that can dissipate sufficient heat for moderate loads on standard FR4 PCBs without additional heatsinking, keeping junction temperature within safe limits at 5.5 V input and 2.8 V output.

When should TLV1117LV28DCYR be chosen over an adjustable LDO regulator for a 2.8 V design?

TLV1117LV28DCYR is preferable when a fixed 2.8 V rail is needed and board space is limited, eliminating 2 external resistors and simplifying layout. Its fixed output reduces component count and tolerances, making it a reliable choice for production designs supplying cameras, Wi-Fi modules, or NFC chips from a 3.3 V or 5 V bus with up to 800 mA demand.
