Product Description

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 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 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, DPAK, D2PAK and D2PAK/A. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25°C.
Features
■ Typical dropout 1.3V (at 3A)
■ Three terminal adjustable or fixed output voltage 1.5V, 1.8V, 2.5V, 3.3V, 5V, 12V.
■ Guaranteed output current up to 3A
■ Output tolerance ±1% at 25°C and ±2% in full temperature range
■ Internal power and thermal limit
■ Wide operating temperature range -40°C to 125°C
■ Package available: TO-220, TO-220FP, DPAK, D2PAK, D2PAK/A
■ Pinout compatibility with standard adjustable VREG
