00 — Overview

What the LT1086-3.3 does

The LT1086x is a 1.5A low dropout positive regulator available in fixed and adjustable versions with output voltages of 2.85V, 3.3V, 3.6V, 5V, and 12V. It features a 1V minimum dropout voltage, 0.015% line regulation, 0.1% load regulation, and ripple rejection exceeding 75dB. The device operates across commercial, industrial, and military temperature ranges. It is typically used as a post regulator for switching supplies, a microprocessor supply, a battery charger, or a constant current regulator. The LT1086x is offered in 3-pin TO-220 and 3-pin DD packages.
