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 LD1085 is supplied in DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C.
