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.

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

Product Detail

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
