PSRR is 65 dB at 100 Hz — this attenuates 100 Hz ripple from a rectified line-frequency supply by a factor of ~1800. For a 2.5V rail feeding a sensitive ADC or PLL, that keeps the output clean enough that the noise floor stays below the converter's LSB step. Above 100 kHz the PSRR rolls off; upstream switching noise at that frequency needs a ferrite bead or LC filter ahead of the LDO. Quiescent current is 100 µA typical — the regulator's own draw is low enough for always-on rails in battery-powered gear, but not as aggressive as a micropower LDO (which would trade dropout or PSRR). The 100 µA Iq is a reasonable middle ground for a 1A part. ## Protection and temperature range Built-in over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection — the UVLO threshold prevents the output from turning on until the input is high enough to keep the pass element in dropout margin, avoiding brown-out conditions on the load.","metaTitle":"TLV117125DCYT 2.5V 1A LDO, SOT-223-4, Active","metaDescription":"Texas Instruments TLV117125DCYT: 2.5V fixed output, 1A LDO, 65dB PSRR at 100Hz, 0.8V dropout max, SOT-223-4, -40 to 125°C, Active.
