LD1117DT12TR ST PMIC - Voltage Regulators - Linear

The LD1117DT12TR from ST is a fixed 1.2 V 800 mA low‑dropout linear regulator in a surface‑mount DPAK package, providing a compact, thermally‑aware power solution for noise‑sensitive circuits. For selection, it features a 1.1 V max dropout, a 15 V input ceiling, 75 dB ripple rejection at 120 Hz, 5 mA quiescent current, ±1 % accuracy, and internal current‑limiting with thermal shutdown. In application, it powers FPGA/MCU core rails, SCSI‑2 terminators, portable medical instruments, handheld devices, automotive ECUs, telecom modules, industrial controllers, and IoT sensor nodes where stable 1.2 V and simple, robust regulation are required.
