Its PSRR profile — 85 dB at 10 Hz rolling to 45 dB at 1 MHz — means it attenuates ripple from upstream switching converters across the audio and low-MHz bands, relevant for noise-sensitive analog front-ends or sensor bias rails. Maximum dropout is 0.2 V at 200 mA, so the input-to-output headroom needs to stay above 200 mV at the full load current to maintain regulation. ## Quiescent budget and thermal envelope Quiescent current is 110 µA typical, with a maximum supply current of 130 µA — the device's own draw stays low enough for always-on battery-powered designs where every microamp counts. Integrated protection includes over-current, over-temperature, and under-voltage lockout (UVLO) — the regulator shuts down safely if the input rail drops below the UVLO threshold or the junction exceeds the thermal limit. ## 6-WSON package and board integration Packaged in a 6-WFDFN (6-WSON) measuring 1.5 mm × 1.5 mm, the TPS727285DSER fits into space-constrained designs like wearable or IoT modules where board area is at a premium. Surface-mount assembly with an enable pin — the regulator can be gated by a GPIO to cut quiescent draw when the load is idle. ROHS3 compliant per the manufacturer's declaration, with no REACH or UL exemptions noted in the available documentation.","metaTitle":"TPS727285DSER LDO, 250mA, 2.85V fixed, 6-WSON","metaDescription":"Texas Instruments TPS727285DSER linear regulator, 250mA output, 2.85V fixed, PSRR 85dB-45dB (10Hz-1MHz), 6-WSON package.
