LT1764AEQ#TRPBF Description

Short technical summary and product information.

The LT1764AEQ#TRPBF is a high-performance 3A linear voltage regulator from Analog Devices, optimized for fast transient response and low noise operation. It features a wide input voltage range from 2.7V to 20V and provides stable output with low dropout voltage.

 

Key electrical characteristics include a 3A output current capability, a typical dropout voltage of 340mV at 3A, and very low output noise of 40µVRMS from 10Hz to 100kHz. The quiescent current is 1mA during normal operation and drops to less than 1µA in shutdown mode. The device supports both fixed output voltages (1.5V, 1.8V, 2.5V, 3.3V) and an adjustable output from 1.21V to 20V.

 

Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting, enhancing reliability. The LT1764AEQ#TRPBF is designed to be stable with output capacitors as low as 10µF, including ceramic types. It is available in TO-220, DD, and FE packages, suitable for various through-hole mounting applications.

 

This regulator is ideal for applications requiring clean power, such as sensitive RF supply applications, post-regulation for switching supplies, and 3.3V to 2.5V logic power supplies.
