Description
The LD1085xx is a low drop voltage regulator
able to provide up to 3 A of output current.
Dropout is guaranteed at a maximum of 1.2 V at
the maximum output current, decreasing at lower
loads. The LD1085xx is pin to pin compatible with
the older 3-terminal adjustable regulators, but has
better performances in term of drop and output
tolerance.
A 2.85 V 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 LD1085xx quiescent current flows
into the load, so increase efficiency. Only a 10 µF
minimum capacitor is need for stability.
The device is supplied in TO-220, TO-220FP,
DPAK, D2PAK and D2PAK/A. On chip trimming
allows the regulator to reach a very tight output
voltage tolerance, within ±1% at 25 °C.
