The LT1764EQ-1.8#PBF is a low dropout (LDO) linear voltage regulator optimized for fast transient response and low noise operation. It can supply up to 3A of output current with a typical dropout voltage of 340mV at 3A. The device features a fixed 1.8V output voltage and operates from an input voltage range of 2.7V to 20V.
Designed for sensitive applications, it offers low output voltage 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 regulator is stable with output capacitors as low as 10µF.
Internal protection circuitry includes over current, over temperature, and reverse polarity protection, eliminating the need for external protection diodes. The LT1764EQ-1.8#PBF is available in a 5-lead TO-263BA (DDPAK) surface mount package, suitable for various power management applications.
Key electrical characteristics include a typical PSRR of 63dB at 120Hz and a maximum dropout voltage of 660mV at 3A. The device is ideal for post-regulation of switching supplies and 3.3V to 2.5V logic power supplies.
