AP7179D  
3A, ULTRA LOW NOISE, HIGH ACCURACY, LDO VOLTAGE REGULATOR  
Description  
Pin Assignments  
The DIODES™ AP7179D is a high output current (3A), low-dropout  
regulator capable of sourcing 3A with 180mV maximum dropout, low-  
noise (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 RF components.

High output accuracy, remote sensing, excellent transient  
performance, and soft-start capabilities also make the AP7179D ideal  
to power digital loads such as field-programmable gate arrays  
(FPGAs), digital signal processors (DSPs), and application-specific  
integrated circuits (ASICs).  
W-QFN3535-20 (Type A1)  
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.
