ADM7155is a linear regulator that operates from a 2.3 V to 5.5 V supply with a maximum output current of 600 mA. The device uses an advanced proprietary architecture that provides high power supply rejection and ultralow noise to achieve excellent line and load transient response with only a 10 μF ceramic output capacitor.
The ADM7155 is available in four models to optimize power dissipation and PSRR performance based on input and output voltage. The selection guide is shown in Table 9 and Table 10.
ADM7155 regulatorTypical output noise is 0.9 μV rms (100 Hz to 100 kHz, fixed output voltage) and a noise spectral density of 1.5 nV/√Hz from 10 kHz to 1 MHz. Available in 8-lead, 3 mm × 3 mm LFCSP and 8-lead SOIC packages, the ADM7155 is not only very compact, but also has excellent thermal performance for low-profile, small applications requiring up to 600 mA output current.
