That extra 20V headroom lets the regulator ride through unregulated 48V telecom rails or 48V nominal industrial buses without a pre-regulator. Output adjusts from 1.25V up to 57V, limited by the input-output differential. The 1.5A continuous output current is typical for powering analog front-ends, sensor supplies, or local post-regulation on a high-voltage rail. ## PSRR and ripple rejection – what 80 dB means PSRR is 80 dB typical at 120 Hz, dropping to 65 dB at higher frequencies. For a 60V rail with 1 Vpp of 120 Hz ripple, the output sees about 100 µVpp — clean enough for most 12-bit analog supplies. ## TO-3 steel can – mounting and thermal path The TO-204AA (TO-3) steel package is a two-lead through-hole can with a metal tab that bolts directly to a heatsink. The tab is electrically connected to the output pin — use an insulating kit if the heatsink is chassis ground. The 12 mA quiescent current is typical for a three-terminal adjustable regulator at this current rating. ## Protection features – over current, over temp, short circuit Built-in over-current, over-temperature, and short-circuit protection are standard for the LM317 family. The regulator survives an output short indefinitely as long as the junction temperature stays below the thermal shutdown threshold.","metaTitle":"LM317HVK STEEL/NOPB – 60V Input","metaDescription":"Texas Instruments LM317HVK STEEL/NOPB: adjustable positive linear regulator, 60V max input, 1.5A output, TO-3 package.
