ADP7104 Low Dropout Linear Regulator

Analog Devices’ positive linear regulators for test, measurement, and noise sensitive applications

Image of Analog Devices ADP7104 Low Dropout Linear RegulatorADI's ADP7104 low dropout (LDO) linear regulator provides up to 500 mA of output current and operates from 3.3 V to 20 V. This high input regulator is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 19 V to 1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1 μF ceramic output capacitor.

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 outputs include: 1.22 V, 1.5 V, 1.8 V, 2.5 V, 3 V, 3.3 V, 5 V, and 9 V. The regulator’s output noise voltage is 15 μVRMS 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 under-voltage lockout function facilitates the 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. The ADP7104 was specifically designed for test, measurement, and noise sensitive applications.
