Diodes Incorporated (Diodes) released a 3A-rated low-dropout (LDO) voltage regulator supporting 4.4µVRMS operation (at 0.8V output). Delivering a clean supply, the AP7179D is highly optimized for powering noise-sensitive components - such as the high-performance SerDes, RF components, and data converters needed for high-speed communications, test and measurement, medical, and video applications. Remote radio units (RRUs), outdoor backhaul units, mMIMO active antenna systems, ultrasound scanners, radar systems, and lab/field instrumentation are among the types of hardware into which it can be incorporated.

The AP7179D has a ±1% output accuracy across line, load, and temperature. This device?s 180mV (maximum) dropout voltage at a 3A load current supports a wide voltage conversion range. Its low-noise reference and error amplifier enables a minimal noise floor.

In addition, its 40dB power supply rejection ratio (PSRR) at 500kHz substantially lowers the coupling of input supply noise to the output.
