Single positive regulator with over-current protection as the only on-chip safeguard — no thermal shutdown or reverse-current blocking is listed, so the downstream load and input transient profile need to stay within the device's SOA. ## 60 dB PSRR at 100 kHz — what the noise rejection means Power-supply rejection ratio is 60 dB at 100 kHz, the frequency where many switching regulators cross over from closed-loop to open-loop attenuation — this LDO attenuates a 100 mV ripple on the input to roughly 100 µV at the output, which is the noise floor for a 12-bit ADC reference rail or an RF supply. Below 100 kHz the PSRR is higher (typical LDO curves show 70+ dB at 1 kHz), so the dominant noise coupling path is the switching-regulator fundamental and its harmonics above the crossover — a pi filter ahead of the LDO helps if the upstream switcher runs at 500 kHz or higher. Operating junction temperature range is -40°C to 125°C, which covers the automotive Grade 1 band — the device can sit under the hood or in an engine-bay ECU that sees 105°C ambient and still have 20°C margin before the junction limit. ## SC-70-5 footprint — board-fit note Available in Tape & Reel (TR) and Cut Tape (CT) options — the TR format suits automated pick-and-place at production volumes, while CT is typical for prototype or low-volume builds.","metaTitle":"TI TPS71530DCKRM3 LDO Regulator, 50mA, 3V Fixed, SC-70-5","metaDescription":"Texas Instruments TPS71530DCKRM3 LDO regulator, 50mA output, 3V fixed, 24V max input.
