The LT1764A series from Linear Technology offers 3A low dropout regulators optimized for fast transient response and low noise operation. These regulators feature a wide input voltage range from 2.7V to 20V and provide an output current of up to 3A with a typical dropout voltage of 340mV at 3A.
Key electrical characteristics include low output voltage noise of 40µVRMS from 10Hz to 100kHz, a quiescent current of 1mA, and less than 1µA in shutdown mode. The devices offer fixed output voltages of 1.5V, 1.8V, 2.5V, and 3.3V, as well as an adjustable output option from 1.21V to 20V.
Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting. The LT1764A regulators are stable with output capacitors as low as 10µF, including ceramic capacitors. They are available in TO-220, DD, and FE packages.
Applications include 3.3V to 2.5V logic power supplies and post-regulation for switching supplies where fast transient response and low noise are critical.
