The LT1963AIQ#TRPBF is an adjustable positive linear low-dropout (LDO) voltage regulator designed for applications requiring fast transient response and low noise. It can supply up to 1.5A of output current with a typical dropout voltage of 340mV.
Key electrical characteristics include a low output noise of 40µVRMS (10Hz to 100kHz) and a quiescent current of 1mA, which drops to less than 1µA in shutdown mode. The output voltage is adjustable from 1.21V to 20V, providing flexibility for various power supply designs.
Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting, enhancing reliability. The regulator is stable with output capacitors as low as 10µF, including ceramic types. It is supplied in a 5-DDPAK surface mount package.
This device is well-suited for post-regulation of switching supplies, 3.3V to 2.5V logic power supplies, and other sensitive RF applications where clean power is essential.
