This means the regulator rejects line-frequency ripple well — a 100 Hz rectified sine wave on the input is attenuated by a factor of ~1800 — but above 10 kHz the rejection drops to about 100×, so upstream switching noise from a buck converter or charge pump will pass through unless a ferrite bead or LC filter is placed ahead of the LDO. For a sensor front-end or audio codec supply where the noise floor matters at 20 kHz and above, the 40 dB PSRR at 100 kHz means the LDO alone is not enough — the input rail must be clean to begin with. ## 200 mA output with dropout headroom Rated 200 mA continuous output with a maximum dropout voltage of 0.4 V at full load. Quiescent current is 80 µA typical, rising to 120 µA maximum supply current. In a battery-powered design drawing 10 µA in sleep, the regulator's own Iq dominates the sleep budget — a load-switch or enable pin to shut down the LDO during sleep extends battery life. ## Industrial temperature range and package constraints The 125°C upper limit means the junction temperature can reach 125°C without derating the output current, but the DSBGA package's thermal resistance (not specified here) will limit how much power can be dissipated at that ambient. Housed in a 5-bump DSBGA (5-UFBGA) package, 0.4 mm pitch typical for this class. The small footprint saves board area but requires a controlled solder-paste stencil and X-ray inspection for voiding — rework is difficult without a hot-air station and a microscope. ## Protection features and enable control Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protection. The UVLO threshold prevents the output from sourcing current when the input rail drops below the regulation headroom — useful in a multi-rail power-up sequence where the 1.8 V or 2.85 V rail must not back-feed into a pre-biased load. An enable pin is provided for sequencing or shutdown. The fixed output configuration means no external feedback divider is needed — the 1.8 V and 2.85 V rails are set internally.","metaTitle":"TPS728180285YZUT LDO, 200mA, 1.8/2.85V, DSBGA-5","metaDescription":"Active-production dual-output LDO, 200 mA, 1.8 V and 2.85 V fixed outputs, 65 dB PSRR at 100 Hz, -40 to 125°C, 5-DSBGA.
