ADM7150ARDZ-3.3-R7 Product Details

The ADM7150ARDZ-3.3-R7 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 loadtransient response with a 10 μF ceramic output capacitor.

The ADM7150ARDZ-3.3-R7 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 ADM7150ARDZ-3.3-R7 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 ADM7150ARDZ-3.3-R7 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.

ADM7150ARDZ-3.3-R7 is a fixed Vout device. For an adjustable Vout version of the ADM7150, see theADM7151.
