Product Summary
The ld1086d2t50tr 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 ld1086d2t50tr 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 ld1086d2t50tr quiescent current flows into the load, so increase efficiency. Only a 10μF 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℃.
