GENERAL DESCRIPTION

The ADM7154 is a linear regulator that operates from 2.3 V to

5.5 V and provides up to 600 mA of load current. Using an

advanced proprietary architecture, it provides high power

supply rejection and ultralow noise, achieving excellent line and

load transient response with only a 10 µF ceramic output capacitor.

The ADM7154 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 600 mA of load current in a small,

low profile footprint.

There are 16 standard output voltages for the ADM7154. The

following voltages are available in stock: 1.2 V, 1.8 V, 2.5 V, 2.8 V,

3.0 V, and 3.3 V. Additional voltages are available by special

order: 1.3 V, 1.5 V, 1.6 V, 2.0 V, 2.2 V, 2.6 V, 2.7 V, 2.9 V, 3.1 V,

and 3.2 V.
