SLR1085
Technical Data
3A Low Dropout Positive Regulator
Data Sheet N1585, Rev. -
Description:
The SLR1085 is a low dropout three terminal regulator with 3A output current capability. The output
voltage is adjustable with the use of a resistor divider or fixed 1.8V, 2.5V and 3.3V. Dropout voltage is
guaranteed to be at maximum of 1.4V with the maximum output current. Its low dropout voltage and
fast transient response make it ideal for low voltage microprocessor applications. Current limit and
thermal protection provide protection against any overload condition that would create excessive
junction temperatures.
Features:
• Dropout Voltage 1.3V at 3A Output Current.
• Fast Transient Response.
• Extremely Tight Line and Load Regulation.
• Current Limiting and Thermal Protection.
• Adjustable Output Voltage or Fixed 1.8V, 2.5Vand 3.3V.
• Standard 3-Pin Power Packages.
Applications:
• Mother Board I/O Power Supplies.
• Microprocessor Power Supplies.
• High Current Regulator.
• Post Regulator for Switching Supply.
Typical application circuit:
Adjustable Voltage Regulator
Fixed Voltage Regulator
