描述 Description

The DIODES? AP7179D is a high output current (3A), low-dropout regulator capable of sourcing 3A with 180mV maximum dropout, lownoise (4.4μVRMS), high output voltage accuracy (1%). The device output voltage is pin-programmable from 0.8V to 3.95V using a PCB layout and adjustable from 0.8V to 5.0V using an external resistor divider. The device supports a lower input voltage of 1.1V, which makes it flexible to use and requires a lower component count.

The device’s low noise (4.4μVRMS), high PSRR, and high output current capability makes it ideal to power noise-sensitive devices such as high-performance serializers and deserializers (SerDes), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and FR components.

High output accuracy, remote sensing, excellent transient performance, and soft-start capabilities also make the AP7179D idealto power digital loads such as field-programmable gate arrays (FPGAs), digital signal processors (DSPs), and application-specificintegrated circuits (ASICs). The enable control and a power-good indicator provide easy and accessible power-sequence control. Output noise immunity is enhanced by adding a bypass capacitor on NR/SS pin.

The AP7179D is packaged in the W-QFN3535-20 (Type A1) package.
