LD1085V18 Datasheet PDF - ST Microelectronics

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 1.2V a 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 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, D2PAK and D2PAK/A. On chip trimming allows the

●regulator to reach a very tight output voltage tolerance, within ±1% at 25°C.
