General Description
• The LD1084 is a series of low dropout positive voltage regulators
with a maximum dropout of 1.5V at 5A of load current.
• The LD1084 series is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V
versions. The fixed versions integrate the adjust resistors. It is also
available in an adjustable version which can set the output voltage
with two external resistors.
• The LD1084 series includes a current limiting circuit and a trimmed
band-gap reference. It also provides thermal limiting protection
against excessive junction temperature.
• The LD1084 series is available in standard packages of DPAK
(TO-252-2), D2PAK-2(TO-263-2) and TO-220-3.
Features
• Low dropout voltage: 1.3V typical at 5A
• Current limiting and thermal protection
• Output current: 5A
• Current limit: 6.5A
• Operation junction temperature: 0 to 125°C
• Line regulation(adj version): 0.015% typical
• Load regulation(adj version): 0.1% typical
• RoHS compliant and halogen free
Applications
• High Efficiency Linear Regulator
• Battery Chargers
• Post Regulation for Switching Supply
• Microprocessor Supply
• Desktop PCs, RISC and Embedded Processors’ Supply
