The PSRR profile — 65 dB at 100 Hz, tapering to 40 dB at 1 MHz — means it attenuates supply ripple across the switching-regulator band, making it a fit for powering analog front-ends, ADCs, or PLL supplies where a clean rail is non-negotiable. ## Dropout headroom and quiescent current trade-off Maximum dropout is 0.14 V at 300 mA, so the input rail needs to stay above 2.64 V across load and temperature to keep the output in regulation. Quiescent current is 15 µA typical — low enough for always-on battery-powered circuits, though the 2 mA maximum supply current at full load should be factored into the system power budget. The SOT-23-5 (SC-74A) package with exposed pad helps spread heat; thermal resistance depends on PCB copper area under the device. ## Protection and control for robust system integration Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protection means the regulator survives output shorts and thermal overload without external clamp diodes. The Enable pin allows the system to gate the rail on/off — useful for sequencing or reducing standby current in multi-rail designs.","metaTitle":"TI TPS7A2025PDBVR LDO, 300mA, 2.5V Fixed, SOT-23-5","metaDescription":"Texas Instruments TPS7A2025PDBVR linear regulator, 300 mA output, 2.5 V fixed, 65 dB PSRR, SOT-23-5.
