Quiescent current draws 500 µA typical, rising to 1 mA maximum including the supply current — this is a moderate Iq for a 400mA LDO, suited to always-on rails where the load current dominates the power budget. ## Package, temperature range, and protection Housed in an 8-VSSOP (3.00mm width MSOP/TSSOP footprint), the part mounts on a standard surface-mount layout with the enable pin available for sequencing the output rail. Integrated over-current and over-temperature protection shut down the pass element before the die exceeds its safe operating area.","metaTitle":"REG113EA-3.3/250 LDO, 3.3V fixed, 400mA, 8-VSSOP","metaDescription":"Texas Instruments REG113EA-3.3/250 LDO regulator, 3.3V fixed output, 400mA, 65dB PSRR at 120Hz, active production.
