Applications
TLV1117LV28DCYR is used to power 2.8 V image sensors, RF front-end modules, and SDIO peripherals in smartphones and embedded systems. Its low dropout of 0.57 V nominal allows regulation from a 3.3 V rail with minimal headroom loss, making it ideal for battery-powered IoT devices. The SOT-223 package provides sufficient thermal mass for up to 800 mA continuous load without an external heatsink in typical PCB layouts.

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.
