Description

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

into the load, so increase efficiency. Only a 10 µF
minimum capacitor is need for stability.

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

2

PAK and D2PAK/A. On chip trimming
allows the regulator to reach a very tight output
voltage tolerance, within ± 1 % at 25 °C.

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 Ta bl e 1 1 (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.
