Description The LD1085 is a low dropout regulator capable of delivering up to 3A of output current. The differential guarantees a maximum maximum output current at a 1.5V maximum, with a lower load reduction. The LD1085 is pin-to-pin compatible with older three-terminal adjustable regulators, but tolerant of long-term drop and output performance for better performance. A 2.85V output version is available for SCSI-2 active termination. Unlike PNP regulators, where the quiescent part of the output current is wasted current, the LD1085 quiescent current flows into the load, thus improving efficiency. Only a minimum capacitance of 10mF is required for stabilization. DPAK provided by the device. On-chip trimming allows the regulator to achieve a very tight output voltage tolerance, within ±2% at 25°C.
