1.5 A low drop positive voltage regulator adjustable and fixed

Features

■ Typical dropout 1.3 V at 1.5 A

■ Three terminal adjustable or fixed output

voltage 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V, 12 V

■ Automotive Grade product: adjustable V

OUT

DPAK

only in TO-220 and DPAK packages

TO-220

D²PAK

■ Guaranteed output current up to 1.5A

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

full temperature range

■ Internal power and thermal limit

D²PAK/A

■ Wide operating temperature range

-40 °C to 125 °C

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

the load, so increase efficiency. Only a 10 µF

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 1 % at 25 °C.

Description

The LD1086 is available as Automotive Grade in

TO-220 and DPAK packages, for the option of

adjustable output voltage whose commercial Part

Numbers are shown in the Table 17 (order

codes). These devices are qualified according to

the specification AEC-Q100 of the Automotive

market, in the temperature range -40 °C to 125

°C, and the statistical tests PAT, SYL, SBL are

performed.

The LD1086 is a low drop voltage regulator able

to provide up to 1.5 A of output current. Dropout is

guaranteed at a maximum of 1.2 V 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 2.85 V 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.
