Description
The LD1086 is a LOW DROP voltage regulator able to provide up to 1.5A of output current. Dropout is guaranteed at a maximum of 1.2V at the maximum output current, decreasing at lower loads. The LD1086 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 LD1086 quiescent current flows into Table 1. Device summary
the load, so increase efficiency. Only a 10F minimum capacitor is need for stability. The device is supplied in TO-220, D2PAK, D2PAK/A and DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within 1% at 25C.
