Description : 7.5A, 5A, 3A LOW DROPOUT POSITIVE ADJUSTABLE REGULATORs View

DESCRIPTION

The LT® 1083 series of POSITIVE ADJUSTABLE REGULATORs are designed to provide 7.5A, 5A and 3A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1V input-to-output differential and the DROPOUT voltage is fully specified as a function

of load current. DROPOUT is guaranteed at a maximum of 1.5V at maximum output current, decreasing at LOWer load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress on both the REGULATOR and power source circuitry under overload conditions.



FEATURES

■ Three-Terminal ADJUSTABLE

■ Output Current of 3A, 5A or 7.5A

■ Operates Down to 1V DROPOUT

■ Guaranteed DROPOUT Voltage at Multiple Current Levels

■ Line Regulation: 0.015%

■ Load Regulation: 0.1%

■ 100% Thermal Limit Functional Test

■ Fixed Versions Available

■ Available in 3-Lead Plastic TO-220, TO-3P and DD Packages

Description : 7.5A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR View

DESCRIPTION

The US1175 product is a 7.5A REGULATOR with extremely LOW DROPOUT voltage using a proprietary Bipolar process that achieves comparable equivalent on resistance to that of discrete MOSFETs. This product is specifically designed to provide well regulated supply for applications requiring very LOW DROPOUT such as 2.8V from 3.3V ATX power supplies where the same efficiency as the switcher can be achieved without the cost and complexity associated with switching REGULATORs. One such application is the new graphic chip sets that requires 2.7V supply such as the Intel I740 chip set.



FEATURES

0.5V DROPOUT at 7.5A (Equivalent of 67mW)

Fast Transient Response

1% Voltage Reference Initial Accuracy

Built-in Thermal Shutdown



APPLICATIONS

3.3V to 2.7V Intel I740 chip set.
