This document introduces the features and characteristics of the LT1086 series products, including 3-terminal adjustable or fixed voltage, 1.5A output current, 1V input-output differential, multiple current levels guaranteed dropout voltage, 0.015% line regulation, 0.1% load regulation, 100% thermal limit functional test,> 75dB ripple rejection, etc.
The LT1086 family of 3‑terminal low‑dropout regulators provides up to 1.5 A output current (0.5 A for the LT1086H) with a guaranteed dropout voltage as low as 1 V. Available in 3‑pin TO‑220 and 3‑pin DD surface‑mount packages, the devices feature excellent line and load regulation, ripple rejection over 75 dB, and built‑in short‑circuit and thermal shutdown protection.
The datasheet includes absolute maximum ratings, detailed electrical characteristics, typical performance curves, and package dimensions. It also offers guidance on required output capacitors for stability and outlines typical applications such as battery chargers, microprocessor supplies, and high‑efficiency linear regulation.
| Output Current | 1.5 A (0.5 A for LT1086H) |
|---|---|
| Line Regulation (typical) | 0.015 % |
| Ripple Rejection | >75 dB |
| Available Packages | 3‑Pin TO‑220 and 3‑Pin DD |
The LT1086 can deliver up to 1.5 A, while the LT1086H version is limited to 0.5 A.
The device is offered in a 3‑pin TO‑220 package and a 3‑pin DD surface‑mount package.
Ripple rejection exceeds 75 dB even at the maximum load current.
