800毫安超低噪聲高PSRR射頻線性穩(wěn)壓器ADM7151數(shù)據(jù)表

　　The ADM7151 is a low dropout （LDO） linear regulator that operates from 4.5 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 in 8-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 800 mA of output current in a small， low profile footprint.
