5 V to 16 V and provides up to 800 mA of output current.
Using an advanced proprietary architecture, it provides high power supply rejection (>90 dB from 1 kHz to 1 MHz), ultralow noise (1.
7 nV√Hz from 10 kHz to 1 MHz), and excellent line and load transient response with a 10 μF ceramic output capacitor.
The output voltage can be set to any voltage between 1.
5 V and 5.
1 V with two resistors.
The ADM7151 is available in two models that optimize power dissipation and PSRR performance as a function of input and output voltage.
See Table 6 and Table 7 for selection guides.
The ADM7151 regulator output noise is 1.
0 μV rms from 100 Hz to 100 kHz, and the noise spectral density is 1.
7 nV/√Hz from 10 kHz to 1 MHz.
The ADM7151 is available i...
