5 / 39 page  LM3404, LM3404HV www.ti.com SNVS465F – OCTOBER 2006 – REVISED MAY 2013 ELECTRICAL CHARACTERISTICS LM3404 VIN = 24V unless otherwise indicated. Typicals and limits appearing in plain type apply for TA = TJ = 25°C. (1) Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are specified by design, test, or statistical analysis.
