The ADM7151 is a low dropout (LDO) linear regulator that operates from 4.5 V to 16 V and provides up to 800 mA of output current. Using an advanced proprietary architecture, it provides high power supply rejection (>90 dB from 1 kHz to 1 MHz), ultralow noise (1.7 nV√Hz from 10 kHz to 1 MHz), and excellent line and load transient response with a 10 μF ceramic output capacitor. The output voltage can be set to any voltage between 1.5 V and 5.1 V with two resistors.The ADM7151 is available in two models that optimize power dissipation and PSRR performance as a function of input and output voltage. See Table 6 and Table 7 for selection guides.The ADM7151 regulator output noise is 1.0 μV rms from 100 Hz to 100 kHz, and the noise spectral density is 1.7 nV/√Hz from 10 kHz to 1 MHz.The ADM7151 is available in 8-lead, 3 mm × 3 mm LFCSP and 8-lead SOIC packages, making it not only a very compact solution, but also providing excellent thermal performance for applications requiring up to 800 mA of output current in a small, low profile footprint.ADM7151 is an adjustable Vout device. For fixed Vout version of the ADM7151, see the ADM7150.Applications Regulated power noise sensitive applications RF mixers, phase-locked loops (PLLs), voltage-controlled oscillators (VCOs), and PLLs with integrated VCOs Clock distribution circuits Ultrasound and other imaging applications High speed RF transceivers High speed, 16-bit or greater ADCs Communications and infrastructure Cable digital-to-analog converter (DAC) drivers
