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 1.5V at

the maximum output current, decreasing at

lower loads. The LD1086 is a pin compatible

with 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 flow into the load, so

increase efficency. Only a 10 µF minimum

capacitor is needed for stability. The device is

supplied in TO-220, D2PAK, D2PAK/A and

DPAK packages. On chip trimming allows the

regulator to reach a very tight output voltage

tolerance, within ± 1% at 25 oC.
