Analog Devices Inc. ADM7150 800mA Ultralow Noise RF Linear Regulator
Analog Devices ADM7150 800mA Ultralow Noise RF Linear Regulator operates from 4.5V to 16V and provides up to 800mA of output current. The ADM7150 uses an advanced proprietary architecture and provides high power supply rejection. The device also provides low noise and achieves excellent line and load transient response with a 10μF ceramic output capacitor. The ADM7150 is available in 1.8V, 2.8V, 3.0V, 3.3V, and 5.0V fixed output. 16 fixed output voltages between 1.5V and 5.0V are available upon request.
