the load, so increase efficiency. Only a 10 uF 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 25 C. The LD1086 is available as Automotive Grade in TO-220 and DPAK packages, for the option of adjustable output voltage whose commercial Part Numbers are shown in the Table 18 (order codes). These devices are qualified according to the specification AEC-Q100 of the Automotive market, in the temperature range -40 C to 125 C, and the statistical tests PAT, SYL, SBL are performed.

Description
The LD1086 is a LOW DROP voltage regulator able to provide up to 1.5 A of output current. Dropout is guaranteed at a maximum of 1.2 V 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 2.85 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 LD1086 quiescent current flows into Table 1. Device summary
