Product details

What this adjustable LDO brings to the rail

Input voltage maxes at 29 V.

Dropout and load — sizing the headroom

The 1.5 V dropout at the full 1.5 A load sets the minimum input-to-output differential. Quiescent current runs 5 mA typical, with a 10 mA maximum supply current.

Built-in over-current, over-temperature, and short-circuit protection cover the common fault modes. The TO-220-3 tab is the ground (output) plane; bolt it to a heatsink if the dissipation exceeds a few watts — the junction-to-case thermal path is designed for tab-mount cooling. Through-hole mounting means hand-assembly or wave-solder; no MSL concerns, no reflow profile to validate. Check the tab clearance if you're potting the board.

ROHS3 compliant, no exemption drama.

Frequently asked questions

What is the maximum output current of LM1086IT-ADJ?

The rated continuous output current is 1.5 A. Dropout at that current is 1.5 V maximum, so plan the input voltage accordingly.

What is LM1086IT-ADJ/NOPB's listed PSRR?

PSRR is 75 dB at 120 Hz, which provides strong rejection of rectified line ripple for analog supply rails.
