STMICROELECTRONICS LD1085P

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 VOUT
only in TO-220 Full Pack package
■
Guaranteed output current up to 3 A
■
Output tolerance ± 1 % at 25°C and ± 2 % in full
temperature range
■
Internal power and thermal limit
■
Wide operating temperature range -40 °C to
125 °C
■
Package available: TO-220, TO-220FP,
DPAK, D2PAK, D2PAK/A
into the load, so increase efficiency. Only a 10 µF
minimum capacitor is need for stability.
■
Pinout compatibility with standard adjustable
VREG
The device is supplied in TO-220, TO-220FP,
DPAK, D2PAK and D2PAK/A. On chip trimming
allows the regulator to reach a very tight output
voltage tolerance, within ± 1 % at 25 °C.

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.
TO-220FP
D2PAK
D2PAK/A
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.
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
