Its maximum dropout voltage is just 99 mV at full load, meaning the input rail needs only about 0.95 V to maintain regulation — critical for low-headroom rails like those fed from a 1.2 V or 1.8 V supply bus. Power supply rejection ratio (PSRR) is 80 dB at 100 Hz, rolling off to 33 dB at 1 MHz. This profile means the LDO effectively filters low-frequency ripple from a switching pre-regulator but passes higher-frequency noise above a few hundred kHz — a consideration when the input comes from a fast-switching buck converter without additional post-filtering. ## Quiescent current, protection, and package Quiescent current is 5.7 µA typical, with a maximum supply current of 620 µA. The low Iq makes this LDO suitable for always-on or battery-backed rails where standing current must stay under 10 µA. Built-in protection includes over-current and over-temperature shutdown, plus a current-limit and enable control feature. The device operates over a junction temperature range of -40 °C to 125 °C, covering industrial and automotive ambient requirements. Packaged in a 6-pin DSBGA (0.67 x 1.12 mm), the TPS7A1485PYBKR is a surface-mount device suited for space-constrained PCBs. The small footprint demands careful PCB layout — the exposed die-attach pad must be soldered to a thermal land on the board to achieve the rated current and dropout performance. ## Active production and sourcing posture Sourced through independent distribution channels. Availability and current pricing are confirmed at the time of RFQ against the buyer's BOM quantity.","metaTitle":"Texas Instruments TPS7A1485PYBKR LDO, 1 A, 0.85 V, DSBGA","metaDescription":"Texas Instruments TPS7A1485PYBKR LDO: 1 A output, 99 mV dropout at 1 A, 5.7 µA quiescent, PSRR 80 dB at 100 Hz.
