Description
The LD1085C is a low drop voltage regulator able to provide up to 3 A of output current. Dropout is guaranteed at a maximum of 1.5 V at the maximum output current, decreasing at lower loads. The LD1085C is pin to pin compatible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance.
A 2.85 V 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 LD1085C quiescent current flows into the load, so increase efficiency. Only a 10 µF 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.

Features
■ Typical dropout 1.3 V (at 3 A)
■ Three terminal adjustable output voltage

■ Output 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
