It is built for applications where a clean, stable low-voltage rail is needed — think sensor front-ends, MCU analog supplies, or RF bias lines. The 80 dB to 45 dB PSRR across 100 Hz to 100 kHz tells you this part is designed to reject supply ripple and switching noise, which matters when the 1.8 V rail shares a board with a buck converter or a digital core. ## Protection set and quiescent draw The TPS79118DBVT packs over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection — a full suite that makes it suitable for industrial or battery-powered gear where fault tolerance is expected. Quiescent current sits at 250 µA, which is moderate for a 100 mA LDO; not the lowest-Iq part for always-on battery duty, but reasonable for a regulated rail that stays enabled during operation. An enable pin lets you gate the output for sequenced power-up or sleep modes. ## Package and mounting The part comes in a 5-pin SOT-23-5 (SOT-753) — a small package that reflows easily under a hot-air station. Pin 1 orientation is marked by a dot on the top. ## Lifecycle and sourcing posture The TPS79118DBVT is listed as Active with ROHS3 compliance. No LTB risk for new designs.","metaTitle":"TPS79118DBVT LDO Regulator, 1.8V Fixed Output, 100mA","metaDescription":"TI TPS79118DBVT linear regulator: fixed 1.8V output, 100mA, PSRR 80dB~45dB (100Hz~100kHz), SOT-23-5, -40~85°C.
