Datasheet Diodes AP7179D

AP7179D
3A, ULTRA LOW NOISE, HIGH ACCURACY, LDO VOLTAGE REGULATOR Pin Assignments 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. 1 SNS 2 OUT OUT GND IN IN 19 18 17 16 Thermal Pad 15 IN 14 EN 1.6V 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). 9 11

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. OUT 20 (Top View) 100mV Description 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. Features Applications 
