Features
Description
The LD1086xx is a low drop voltage regulator
capable of providing 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 LD1086xx is pin-to-pin compatible with
older 3-terminal adjustable regulators, but has
better performance in terms of drop and output
tolerance. The 2.85 V output version is suitable for
SCSI-2 active terminations. Unlike PNP
regulators, where a part of the output current is
wasted as quiescent current, the LD1086xx
quiescent current flows into the load, increasing
efficiency. Only a 10 µF (minimum) capacitor is
needed for stability. The device is available in a
TO-220, D²PAK, D²PAK/A or DPAK package. On-
chip trimming allows the regulator to reach a very
Table 1.
