LD1085 - 3A low drop positive voltage regulator
The LD1085 is a low drop voltage regulator able to provide up to 3 A of output current.
Dropout is guaranteed at a maximum of 1.2 V at the maximum output current, decreasing at lower loads.
The LD1085 is pin-to-pin compatible with the older 3-terminal adjustable regulators, but offers better perform
LD1085 3 A low drop positive voltage regulator: adjustable and fixed TO-220 TO-220FP Datasheet - production data Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1085 quiescent current flows into the load, thus increase efficiency.
Only a 10 µF minimum capacitor is need for stability.
The device is supplied in TO-220, TO-220FP, D²PAK and D²PAK/A packages.
On-chip trimming allows the regulator to reach a very tight output voltage tolerance, withi
