GENERAL DESCRIPTION

¹Adj means adjustable.

The ADP7156 is a linear regulator that operates from 2.3 V to 5.5 V

and provides up to 1.2 A of output 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 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 ꢀV 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.
