DESCRIPTION
The LD1085 is a LOW DROP Voltage Regulator
able to provide up to 3A of Output Current.
Dropout is guaranteed at a maximum of 1.5V at
the maximum output current, decreasing at lower
loads. The LD1085 is pin to pin compatible with
the older 3-terminal adjustable regulators, but has
better performances in term of drop and output
tolerance .
A 2.85V output version is suitable for SCSI-2
active termination. Unlike PNP regulators, where
a partof the output current is wasted as quiescent
current, the LD1085 quiescent current flows into
the load, so increase efficiency. Only a 10
μ
F
minimum capacitor is need for stability.
The device is supplied in DPAK. On chip trimming
allows the regulator to reach a very tight output
voltage tolerance, within
