Maximum dropout voltage is 2.5V at the full 180 mA load, meaning the input rail must stay at least 2.5V above 5V (i.e., ≥7.5V) to maintain regulation across all conditions. The 16.5V maximum input gives headroom for 12V or 15V intermediate rails without an external pre-regulator. ## Ripple rejection and protection suite Power supply rejection ratio (PSRR) is 60 dB at 120 Hz, which attenuates full-wave rectifier ripple by a factor of 1000. For a 1 Vpp ripple on the input, the output sees roughly 1 mVpp — adequate for powering analog front-ends or reference circuits that are sensitive to line-frequency hum. On-chip protection includes over-temperature shutdown, reverse polarity protection, and short-circuit current limiting. These features allow the regulator to survive a miswired battery connection or a sustained output short without external clamp diodes. ## Temperature grade and package fit The enable control pin (active high) lets a microcontroller or supervisor IC gate the output rail, reducing quiescent draw in sleep modes. Output configuration is positive fixed, single regulator.","metaTitle":"Texas Instruments LM9074MX Fixed 5V LDO, 180mA, 14-SOIC","metaDescription":"Texas Instruments LM9074MX fixed 5V LDO regulator, 180mA output, 60dB PSRR at 120Hz, -40°C to 125°C, 14-SOIC.
