LD1085CXX 3A LOW DROP ADJUSTABLE POSITIVE VOLTAGE REGULATOR

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
