Maximum dropout voltage is 0.30V at the full 1.5A load, meaning the input must stay at least 300 mV above 1.5V across the operating range to maintain regulation — a 1.8V rail is the practical minimum input. ## PSRR and quiescent draw for noise-sensitive rails Power-supply rejection ratio is 63 dB at 100 Hz, which attenuates 100 Hz ripple from a mains-derived input by a factor of roughly 1400 — relevant for analog front-ends or precision bias supplies where line-frequency noise couples into the output. Quiescent current is 125 µA typical; the regulator's own draw stays under 0.01% of the full output current, so it does not materially affect efficiency in always-on 1.5A loads. ## Control, protection, and temperature grade Control features include Enable, Power Good, and Reset Output — the Power Good flag asserts when the output is within regulation, useful for sequencing downstream rails or holding a microcontroller in reset until the 1.5V bus is stable. On-chip protection covers Over Current, Over Temperature, and Reverse Polarity — the reverse-polarity clamp protects the regulator if the input is accidentally reversed, a safeguard for battery-powered or field-wired supplies. ## Package and board-fit: 20-HTSSOP with exposed pad Surface-mount assembly; the tube packaging (50 units per tube) is standard for prototype and low-to-mid volume production runs. ## Active lifecycle and compliance documentation ROHS3 compliant; the manufacturer provides full RoHS, REACH, and material declaration documentation through its standard compliance portal.","metaTitle":"TPS75315QPWP LDO, 1.5V Fixed Output, 1.5A, 20-HTSSOP","metaDescription":"Texas Instruments TPS75315QPWP LDO regulator, 1.5V fixed output, 1.5A, 63dB PSRR at 100Hz.
