LT1764EQ-2.5 Description
The LT ?1764 is a low dropout regulator optimized for a fast transient response. The device is capable of supplying 3A of output current with a dropout voltage of 340mV. The 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 LT1764 has very low output voltage noise which makes the device ideal for
sensitive RF supply applications.
