PINOUT COMPATIBILITY WITH STANDARD

ADJUSTABLE VREG

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 LD1085 quiescent current flows into

the load, so increase efficiency. Only a 10µF

minimum capacitor is need for stability.

DESCRIPTION

The LD1085 is a LOW DROP Voltage Regulator

able to provide up to 3A of Output Current.

Dropout is guaranteed at a maximum of 1.5V at

the maximum output current, decreasing at lower

loads. The LD1085 is pin to pin compatible with

the older 3-terminal adjustable regulators, but has

better performances in term of drop and output

tolerance .

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

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.
