View Datasheet Manufacturer Site View Pricing & Stock

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 ceramicoutput capacitor.The ADP7157 is available in four models that optimize powerdissipation and PSRR performance as a function of the inputand output voltage.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 avery compact solution, but also providing excellent thermalperformance for
