ADM7150:  800 mA, Ultra Low Noise/High PSRR LDO

Product Details

Product Status:Recommended for New Designs

The ADM7150 is a low dropout 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, they provide high power supply rejection, low noise, and achieve excellent line and load transient response with a 10 μF ceramic output capacitor.

The ADM7150 is available in 1.8 V, 2.8 V, 3.0 V, 3.3 V and 5.0 V fixed output. 16 fixed output voltages between 1.5 V and 5.0 V are available upon request.

The ADM7150 regulator typical output noise is 1.0 μVrms from 100Hz to 100KHz for fixed output voltage options and <1.7nV/√Hz noise spectral density above 10 KHz. The ADM7150 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.

ADM7150 is a fixed Vout device. For an adjustable Vout version of the ADM7150, see the ADM7151.
