It comes in a 4-DSBGA package and is rated for the industrial temperature range of -40°C to 85°C. This part is built for noise-sensitive supply rails: its 55 dB PSRR at 10 kHz means it attenuates switching-regulator ripple well into the audio-frequency band, making it a candidate for powering analog front-ends, codec supplies, or sensor bias lines where a clean 1.8 V is critical. ## Dropout and quiescent — the headroom numbers Maximum dropout is 0.25 V at the full 200 mA load. Quiescent current sits at 75 µA, low enough for always-on peripherals in battery-operated gear. The enable pin (Control Features) lets the system shut down the regulator entirely, pulling near-zero current when the rail is not needed. ## Lifecycle and sourcing — active, no LTB watch Texas Instruments lists this part as Active with a ROHS3 compliance rating.","metaTitle":"LP5990TMX-1.8/NOPB LDO Regulator, 1.8V 200mA, 55dB PSRR","metaDescription":"LP5990TMX-1.8/NOPB linear regulator: fixed 1.8V output, 200mA, 55dB PSRR at 10kHz, 0.25V dropout.
