LD1086xx

1.5A Low drop positive voltage regulator adjustable and fixed

Features

■ Typical dropout 1.3V at 1.5A

■ Three terminal adjustable or fixed output

voltage 1.5V, 1.8V, 2.5V, 3.3V, 3.6V, 5V, 8V,

9V, 12V.

DPAK

■ Guaranteed output current up to 1.5A

TO-220

D²PAK

■ Output tolerance 1ꢀ at 25°C and 2ꢀ in full

temperature range

■ Internal power and thermal limit

■ Wide operating temperature range

-40°C to 125°C

D²PAK/A

■ Package available: TO-220, D PAK, D PAK/A,

DPAK

the load, so increase efficiency. Only a 10µF

minimum capacitor is need for stability. The

device is supplied in TO-220, D PAK, D PAK/A

and DPAK. On chip trimming allows the regulator

to reach a very tight output voltage tolerance,

within 1ꢀ at 25°C.

■ Pinout compatibility with standard adjustable

VREG

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

Table 1.
