Description : 7.5A Low Dropout Voltage Regulator

Description
The Bay Linear B1083 is Monolithic Low power 7.5A Adjustable and fixed NPN Voltage Regulator that are easy to use with minimum external components. 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 a maximum output current. Current limit is trimmed, minimizing the stress on both the Regulator and power source circuitry under overload conditions. It is suitable for applications requiring a well-regulated positive output Voltage with Low input-output differential Voltage.

Description : 7.5A ULTRA Low Dropout POSITIVE ADJUSTABLE Regulator

DESCRIPTION
The IRU1175 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 chipsets that requires 2.7V supply such as the Intel I740 chipset.

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 chipset

Description : 7.5A ULTRA Low Dropout POSITIVE ADJUSTABLE Regulator WITH SHUTDOWN INPUT

DESCRIPTION
The IRU1176 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. The IRU1176 also provides a convenient shutdown pin that alLows the Regulator to be shutdown and reduce the input current consumption. Unlike the PNP type Regulators this device does not have high quiescent current during the start up mode making it ideal for applications where there is limited current capability such operation from the 5V standby supply of the computer power supply. One application is the new generation of RDRAM memory that needs to provide 2.5V from 3.3V input and be able to operate from 5VSB as well.

FEATURES
■ Guaranteed <0.65V Dropout at 7.5A
■ Fast Transient Response
■ 1% Voltage Reference Initial Accuracy
■ Built-In Thermal Shutdown

APPLICATIONS
■ 3.3V to 2.7V Intel I740 Chip Set
