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, DPAK or DFN8 (4x4

in TO-220

mm) package. On-chip trimming allows the
regulator to reach a very tight output voltage
tolerance; within ± 1 % at 25 °C. The LD1086xx is
available as automotive grade for adjustable
output voltages in the TO-220 and DPAK
packages. The PAT, SYL, SBL statistical tests
have been performed, and the devices are
qualified according to the AEC-Q100 specification
for the automotive market in the temperature
range of - 40 °C to 125 °C.
