20 V, 500 mA, Low Noise, CMOS LDO
The ADP7104 is available in seven fixed output voltage options and an adjustable version, which allows output voltages that range from 1.22 V to VIN − VDO via an external feedback divider.
The ADP7104 output noise voltage is 15 μV rms and is independent of the output voltage. A digital power-good output allows power system monitors to check the health of the output voltage. A user programmable precision undervoltage lockout function facilitates sequencing of multiple power supplies.
The ADP7104 is available in 8-lead, 3 mm × 3 mm LFCSP and 8-lead SOIC packages. The LFCSP offers a very compact solution and also provides excellent thermal performance for applications requiring up to 500 mA of output current in a small, low-profile footprint.
- Regulation to noise sensitive applications:
ADC, DAC circuits, precision amplifiers, high frequency oscillators, clocks and PLLs
- Communications and Infrastructure
- Medical and Healthcare
- Industrial and Instrumentation

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.
Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.
