DESCRIPTION

The LD1085 is a LOW DROP Voltage Regulator able to provide up to 3A of Output Current. Dropout is guaran teed at a maximum o f 1.2V at the maximum output current, decreas ing at lower loads. The LD1085 is pin to pin compat ible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance.

TO-220

D2PAK D2PAK/A

TO-220FP

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 LD1085 quiescent current flows into the load, so increase efficiency. Only a 10µF minimum capacitor is need for stability. The device is supplied in TO-220, TO-220FP,

PAK and D2PAK/A. On chip t rimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25°C.
