What this three-terminal regulator does in your rail
It delivers up to 1.5 A output current with an adjustable output range from 1.25 V to 37 V, set by two external resistors. Built-in protection includes over-current, over-temperature, and short-circuit limiting, so it can survive a momentary output short without external crowbar circuitry.
Output range and input limits — what fits your rail
Output is adjustable from 1.25 V to 37 V, matching the maximum input voltage rating of 37 V. Quiescent current is 10 mA typical — this flows to ground and does not pass through the load, but it does add to the total input current budget.
PSRR and noise — where the 64 dB at 120 Hz matters
Power-supply rejection ratio is 64 dB at 120 Hz.
Temperature grade and package — board-fit check
The TO-220-3 package (through-hole) requires a heatsink for loads above about 0.5 A at elevated ambient — the tab is ground and can be bolted to a chassis or clip-on heatsink.
