The ADM7155 is an adjustable linear regulator that operates from 2.3 V to 5.5 V and provides up to 600 mA of load current. Output voltages from 1.2 V to 3.4 V are possible depending on the model. 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 ADM7155 is available in four models that optimize power dissipation and PSRR performance as a function of input and output voltage. See Table 9 and Table 10 for selection guides.
The ADM7155 regulator typical output noise is 0.9 μV rms from 100 Hz to 100 kHz for fixed output voltage options and 1.5 nV/√Hz for noise spectral density from 10 kHz to 1 MHz.
The ADM7155 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.
