LD1085xx

3 A low drop positive voltage regulator adjustable and fixed

Features

■ Typical dropout 1.3 V (at 3 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

only in TO-220 Full Pack package

TO-220

TO-220FP

■ Guaranteed output current up to 3 A

■ 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

DPAK

D²PAK

125 °C

■ Package available: TO-220, TO-220FP,

into the load, so increase efficiency. Only a 10 µF

minimum capacitor is need for stability.

DPAK, D PAK, D PAK/A

■ Pinout compatibility with standard adjustable

The device is supplied in TO-220, TO-220FP,

VREG

DPAK, D PAK and D PAK/A. On chip trimming

allows the regulator to reach a very tight output

voltage tolerance, within 1 ꢀ at 25 °C.

Description

The LD1085xx is available as Automotive Grade

in TO-220FP package only, for the option of

adjustable output voltage whose commercial part

number is shown in the Table 11 (order codes).

This device is 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 LD1085xx is a low drop voltage regulator

able to provide up to 3 A of output current.

Dropout is guaranteed at a maximum of 1.2 V at

the maximum output current, decreasing at lower

loads. The LD1085xx 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 LD1085xx quiescent current flows

Table 1.
