Its 85 dB power-supply rejection ratio at 1 kHz means ripple from a switching converter upstream is attenuated by a factor of roughly 18,000 — enough to keep a 10 mVpp switching artifact below 1 µV at the regulator output, which matters for analog front-ends or ADC reference rails that cannot tolerate supply noise. ## Quiescent current and always-on duty Quiescent current is 28 µA typical — low enough that the regulator's own draw does not dominate the sleep-state budget in a battery-powered sensor node that wakes briefly to take a reading then returns to deep sleep. The enable pin lets a downstream controller gate the output entirely, cutting Iq to near zero when the rail is not needed. Input voltage range extends to 10 V max, so the part can run from a 5 V or 9 V rail without a pre-regulator. The 2.5 V fixed output is common for powering the core of a low-voltage MCU or the analog supply of a small mixed-signal IC. ## Protection set and temperature grade On-chip protection covers overcurrent, overtemperature, and reverse polarity — the reverse-polarity clamp means the regulator survives a swapped battery connection without an external Schottky diode on the input. The SOT-23-5 package (SC-74A) is a standard five-pin small-outline transistor footprint. Board layout is straightforward: input and output capacitors close to the pins, the enable pin pulled high if unused, and the thermal path through the PCB copper rather than an exposed pad.","metaTitle":"Texas Instruments TPS79025DBVT LDO Regulator, 2.5V 50mA","metaDescription":"Texas Instruments TPS79025DBVT fixed-output LDO, 2.5V at 50mA, 85dB PSRR at 1kHz.
