800 mA, Ultra Low Noise/High PSRR Adjustable Vout LDO

Manufactured by:

Product Details

The ADM7151 is a low dropout linear regulator that operates from 4.5 V to 16V and provides up to 800mA of output current. Using an advanced proprietary architecture, they provide high power supply rejection, low noise, and achieve excellent line and load transient response with a 10 μF ceramic output capacitor. The output voltage may be set to any voltage between 1.5V and 5.1V with two resistors.

The ADM7151 is available in 2 models that optimize power dissipation and PSRR performance as a function of input and output voltage.The ADM7151 regulator output noise is 1.0 μVrms (100Hz to 100KHz) and 1.7nV/√Hz noise spectral density above 10KHz.

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 800mA of output current in a small, low-profile footprint.

ADM7151 is an adjustable Vout device. For fixed Vout version of the ADM7151, see the ADM7150.

Product Details

The ADM7150CP-EVALZ and ADM7151CP-04-EVALZ evaluation boards are used to demonstrate the functionality of the ADM7150 and ADM7151 linear regulators, respectively.

Simple device measurements, such as line and load regulation, dropout, and ground current, can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistors.

For more details about the linear regulators, refer to the ADM7150 and ADM7151 data sheets.

Note:ADM7151 is adjustable and requires two resistors to set the output voltage
