Features, Applications

The 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 at a 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 limiting and thermal protection provides protection against any overload condition that would create excessive junction temperatures.

Dropout Voltage 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, 2.5V and 3.3V. Standard 3-Pin Power Packages.
