Product Summary
The LT1764AEQ is a low dropout regulator optimized for fast transient response. The device is capable of supplying 3A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to <1μA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the LT1764AEQ has very low output voltage noise which makes the device ideal for sensitive RF supply applications. The LT1764AEQ regulator is available in 5-lead TO-220 and DD packages, and 16-lead FE packages. Applications of the LT1764AEQ are: 3.3V to 2.5V Logic Power Supply, Post Regulator for Switching Supplies.
