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 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 DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C.

■ TYPICAL DROPOUT 1.3V (AT 3A)
■ THREE TERMINAL ADJUSTABLE OR FIXED OUTPUT VOLTAGE 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 3.6V, 5V, 8V, 9V, 12V.
■ GUARANTEED OUTPUT CURRENT UP TO 3A
■ OUPUT TOLERANCE ±2% AT 25°C AND ±3% IN FULL TEMPERATURE RANGE
■ INTERNAL POWER AND THERMAL LIMIT
■ WIDE OPERATING TEMPERATURE RANGE -40°C TO 125°C
■ PACKAGE AVAILABLE : DPAK
■ PINOUT COMPATIBILITY WITH STANDARD ADJUSTABLE VREG
