Frequently Asked Questions
How much dropout voltage does the LD1117S33TR need to maintain regulation?
The LD1117S33TR needs a maximum dropout of 1.2 V, with a nominal 1.1 V, between its input and the fixed 3.3 V output while delivering up to 0.8 A of load current.
How is the LD1117S33TR packaged for board mounting?
The LD1117S33TR ships in a 3-pin SOT223 surface-mount package, letting designers mount a fixed 3.3 V, 0.8 A linear regulator directly onto compact PCBs alongside 4.75 V to 15 V input sources.
Why should buyers account for lead time on the LD1117S33TR?
STMicroelectronics quotes a standard factory lead time of about 12 weeks for the LD1117S33TR, so buyers sourcing this fixed 3.3 V, 0.8 A SOT223 regulator should order ahead of production runs to avoid shortages.
Which circuits typically rely on the LD1117S33TR for power?
Microcontroller boards, sensor modules, and communication interfaces that need a clean 3.3 V rail from a 4.75 V to 15 V input commonly rely on the LD1117S33TR's 0.8 A fixed linear regulation.
