It comes in a SOT-23-5 package and operates over a junction temperature range of -40°C to 125°C. Key features include an enable pin for power sequencing, a maximum dropout voltage of 0.2 V at full load, and a quiescent current of 15 µA that keeps the overhead low in always-on or battery-powered designs. Protection circuits cover over-current, over-temperature, and under-voltage lockout (UVLO). ## PSRR across the band — the noise-rejection story The PSRR is specified at 65 dB at 100 Hz, rolling off to 40 dB at 1 MHz. That frequency range matters when the input rail carries switching-regulator ripple or digital noise from nearby clocks. A regulator with strong PSRR into the MHz region saves you a post-filter LC stage on sensitive analog, RF, or data-converter supply rails. ## Lifecycle and compliance — no LTB clock ticking The TPS7A20185PDBVR is listed as Active in production with ROHS3 compliance. There is no last-time-buy notice or end-of-life signal on this part.","metaTitle":"TPS7A20185PDBVR LDO Regulator, 1.85V Fixed Output, 300mA","metaDescription":"TI TPS7A20185PDBVR LDO: 1.85V fixed output, 300mA, 0.2V dropout, 15µA Iq, PSRR 65dB-40dB (100Hz-1MHz).
