LT3078 Description
The LT®3078 is a low voltage, ultra-low noise, high power-supply rejection ratio (PSRR), and ultra-fast transient response linear regulator. The device supplies up to 5A with a typical dropout voltage of 55mV. A 4.7µF reference bypass capacitor decreases output voltage noise to 1.3µVRMS (10Hz to 100kHz).
