Its 2 µA quiescent current makes it a fit for battery-backed or always-on domains — think a sensor bias rail, a small MCU core, or a keep-alive supply on an industrial control board where every microamp is budgeted. The fixed output eliminates the feedback divider, saving two resistors and a noise-injection path. Output noise rejection is rated at 50 dB at 100 Hz, which is modest for an LDO — enough to clean up ripple from a rectified mains or a switching pre-regulator, but not enough for a sensitive analog front-end without additional filtering. The part includes over-current and reverse polarity protection, practical for field-wired modules where a supply reversal is possible. ## Package and rework — SC-70-5 Housed in a 5-pin SC-70-5 (SOT-353), this is a small surface-mount package. Hand rework is possible with a fine-tip iron or hot air, but the pad layout needs to be clean — the part is light and can shift during reflow if paste volume is uneven. Pin 1 orientation is marked by a bevel on the top surface; verify the footprint against the supplier package drawing before the board goes out. ## Lifecycle and sourcing Marked as active and ROHS3 compliant.","metaTitle":"TPS797285DCKT LDO Regulator, 2.85V Fixed Output, 50 mA","metaDescription":"TI TPS797285DCKT LDO regulator, fixed 2.85V output, 50mA, 2µA quiescent current, SC-70-5 package.
