LD1086xx 1.5A Low drop positive voltage regulator adjustable and fixed Features ■ Typical dropout 1.3V at 1.5A ■ Three terminal adjustable or fixed output voltage 1.5V, 1.8V, 2.5V, 3.3V, 3.6V, 5V, 8V, 9V, 12V. ■ Guaranteed output current up to 1.5A DPAK ■ Output tolerance ±1% at 25°C and ±2% in full temperature range ■ Internal power and thermal limit ■ Wide operating temperature range -40°C to 125°C ■ Package available: TO-220, D2PAK, D2PAK/A, DPAK ■ Pinout compatibility with standard adjustable VREG 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. TO-220 D2PAK/A D2PAK 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°C. 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.
