Output voltage adjusts from 0 V up to 38.5 V. ## PSRR profile — where it cleans and where it doesn't PSRR starts at 90 dB at 120 Hz and rolls off to 20 dB by 1 MHz. That 90 dB at line frequency knocks down the 120 Hz ripple from a full-wave rectifier. ## Protection set covers field faults Over-current, over-temperature, reverse polarity, and short-circuit protection are all built in. Reverse polarity protection saves a board when a field tech lands the supply backwards. This part carries an Active lifecycle status and ROHS3 compliance. No last-time-buy notice is active.","metaTitle":"LT3082IST#PBF Linear Regulator, 200mA Adjustable, SOT-223","metaDescription":"LT3082IST#PBF positive adjustable linear regulator, 200mA output, 40V max input, 38.5V output max.
