GENERAL DESCRIPTION
The ADP7157 is an adjustable linear regulator that operates from
2.3 V to 5.5 V and provides up to 1.2 A of output current. Output
voltages from 1.2 V to 3.3 V are possible depending on the model.
Using an advanced proprietary architecture, the device provides
high power supply rejection and ultralow noise, achieving excellent
line and load transient response with only a 10 µF ceramic
output capacitor.
The ADP7157 is available in four models that optimize power
dissipation and PSRR performance as a function of the input
and output voltage. See Table 9 and Table 10 for selection guides.
The typical output noise the ADP7157 regulator 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 ADP7157 is available in 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.
