Diodes Incorporated has released a 3A-rated low-dropout (LDO) voltage regulator supporting 4.4\u00b5VRMS operation (at 0.8V output). Delivering a clean supply, the AP7179D<\/a><\/strong> is highly optimised 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.<\/p>\n\n\n\n

The AP7179D has a \u00b11% 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.<\/p>\n\n\n\n

There are two output voltage selection modes for this LDO: pin-programmable between 0.8V and 3.95V, or adjustable using an external resistor divider from 0.8V to 5.5V. The resulting flexibility significantly reduces the number of accompanying components needed.<\/p>\n\n\n\n

The device’s low output noise mitigates both power-supply-generated phase noise and clock jitter. Because of this, alongside its high-current capabilities, this device is compatible with high-performance processors, such as FPGAs, ASICs, and DSPs.<\/p>\n\n\n\n

The AP7179D is housed in a compact 20-pin W-QFN3535 (Type A1) package.<\/p>\n","protected":false},"excerpt":{"rendered":"
