STMicroelectronics LD1117 Series Datasheet
The LD1117 is a low‑dropout positive voltage regulator capable of delivering up to 800 mA. It is offered in fixed output versions (1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.0 V, 3.3 V, 5.0 V) and an adjustable version with a 1.25 V reference. The devices are supplied in SOT‑223, DPAK, SO‑8 and TO‑220 packages, with thermal‑optimized designs for surface‑mount applications.
The document contains detailed electrical characteristics, absolute maximum ratings, thermal data, pin‑out diagrams, and typical application circuits for each voltage version. Revision history and ordering codes are also provided, making it a comprehensive reference for designers and engineers.
