Description

The LD1086 is a LOW DROP voltage regulator

able to provide up to 1.5A of output current.

Dropout is guaranteed at a maximum of 1.2V at

the maximum output current, decreasing at lower

loads. The LD1086 is pin to pin compatible with

the older 3-terminal adjustable regulators, but has

better performances in term of drop and output

tolerance.

A 2.85V output version is suitable for SCSI-2

active termination. Unlike PNP regulators, where

a part of the output current is wasted as quiescent

current, the LD1086 quiescent current flows into

TO-220

D2PAK/A

the load, so increase efficiency. Only a 10µF

minimum capacitor is need for stability. The

device is supplied in TO-220, D2PAK, D2PAK/A

and DPAK. On chip trimming allows the regulator

to reach a very tight output voltage tolerance,

within ±1% at 25°C.
