Analog Devices LT8610A

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). The wide bandwidth and high PSRR deliver the best performance without the need of bulky capacitors, which save space and cost. The LT3078 is ideal for powering high performance FPGAs, data converters, RF, and all noise sensitive signal chain applications.
