ADP7156 Data Sheet
FEATURES TYPICAL APPLICATION CIRCUIT APPLICATIONS
Regulation to noise sensitive applications: phase-locked
loops (PLLs), voltage controlled oscillators (VCOs), and
PLLs with integrated VCOs
Communications and infrastructure
Backhaul and microwave links There are 16 standard output voltages for the ADP7156. The
following voltages are available from stock: 1.2 V, 1.8 V, 2.0 V,
2.5 V, 2.8 V, 3.0 V and 3.3 V. Additional voltages available by
special order are 1.3 V, 1.5 V, 1.6 V, 2.2 V, 2.6 V, 2.7 V, 2.9 V,
3.1 V, and 3.2 V.
The ADP7156 regulator typical output noise is 0.9 μV rms
from 100 Hz to 100 kHz and 1.7 nV/√Hz for noise spectral
density from 10 kHz to 1 MHz. The ADP7156 is available in a
10-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
1.2 A of output current in a small, low profile footprint. VOUT
