LD1086xx
1.5A Low drop positive voltage regulator adjustable and fixed
Features
■ Typical dropout 1.3V at 1.5A
■ Three terminal adjustable or fixed output
voltage 1.5V, 1.8V, 2.5V, 3.3V, 3.6V, 5V, 8V,
9V, 12V.
DPAK
■ Guaranteed output current up to 1.5A
TO-220
D2PAK
■ Output tolerance 1ꢀ at 25°C and 2ꢀ 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 10µF
minimum capacitor is need for stability. The
device is supplied in TO-220, D PAK, D PAK/A
and DPAK. On chip trimming allows the regulator
to reach a very tight output voltage tolerance,
within 1ꢀ at 25°C.
■ Pinout compatibility with standard adjustable

Description
The LD1086 is a LOW DROP voltage regulator
able to provide up to 1.5A of output current.
Dropout is guaranteed at a maximum of 1.2V 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 2.85V 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 LD1086 quiescent current flows into
Table 1.
