Its maximum dropout of 1.2V at full load means the input rail needs to stay at least 1.2V above the set output voltage to maintain regulation — a common gotcha when squeezing a 3.3V rail from a 5V supply with margin. The 75dB PSRR at 120Hz gives good line-frequency ripple rejection, useful when this LDO sits after a rectifier and bulk capacitor in a linear supply chain. ## Output range and protection The part includes over-current and over-temperature protection, so it folds back gracefully under a short or thermal runaway. Housed in a TO-263-3 DDPAK (D²Pak) surface-mount package with an exposed tab. The /NOPB suffix confirms ROHS3 compliance and lead-free assembly. It is a current-production TI device, so new designs can commit the BOM line without near-term obsolescence risk.","metaTitle":"LM1117S-ADJ/NOPB Adjustable LDO Regulator, 800mA, TO-263","metaDescription":"TI LM1117S-ADJ/NOPB adjustable positive LDO, 800mA output, 1.2V max dropout, 75dB PSRR at 120Hz.
