Datasheet - production data
Description
The LD1086 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 LD1086 is pin-to-pin compatible with
older 3-terminal adjustable regulators, but has
better performance in terms of drop and output
tolerance. Unlike PNP regulators, where a part of
the output current is wasted as quiescent current,
the LD1086 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 mm) package. 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 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.
