Product Details
TThe 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.
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.
The ADM7154 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 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.
Applications
- Regulation to noise sensitive applications: PLLs, VCOs, and PLLs with integrated VCOs
- Communications and infrastructure
- Backhaul and microwave links
