Description
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.
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
only in TO-220 and DPAK packages
Guaranteed output current up to 1.5A
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

the load, so increase efficiency. Only a 10 µF
minimum capacitor is need for stability. The
device is supplied in TO-220, D
and DPAK. On chip trimming allows the regulator
to reach a very tight output voltage tolerance,
within ± 1 % at 25 °C.
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
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.
