It comes in a TO-252-3 (DPak) surface-mount package with an exposed tab for thermal dissipation. Maximum dropout is 1.2 V at the full 800 mA load, so the input rail must stay above 4.05 V to maintain regulation. Quiescent current sits at 5 mA typical, with a 10 mA supply-current ceiling — not a low-Iq part for battery standby, but fine for always-on industrial or test equipment rails. Built-in over-current and over-temperature protection keep the die safe under a shorted output or a stalled fan load.","metaTitle":"LM1117DTX-2.85/NOPB LDO Regulator, 2.85V Fixed, 800mA","metaDescription":"Texas Instruments LM1117DTX-2.85/NOPB fixed-output LDO regulator, 2.85V, 800mA, PSRR 75dB at 120Hz.
