AP7179D 3A, ULTRA LOW NOISE, HIGH ACCURACY, LDO VOLTAGE REGULATOR Description Pin Assignments
The DIODES™ AP7179D is a high output current (3A), low-dropout
(Top View)
regulator capable of sourcing 3A with 180mV maximum dropout, low- noise (4.4μVRMS), high output voltage accuracy (1%). The device T T D output voltage is pin-programmable from 0.8V to 3.95V using a PCB U U N O O G IN IN layout and adjustable from 0.8V to 5.0V using an external resistor 0 9 8 7 6 2 1 1 1 1 divider. The device supports a lower input voltage of 1.1V, which makes it flexible to use and requires a lower component count. OUT 1 15 IN SNS 2 14 EN The device’s low noise (4.4μVRMS), high PSRR, and high output current capability makes it ideal to power noise-sensitive devices FB 3 Thermal Pad 13 NR/SS such as high-performance serializers and deserializers (SerDes), PG 4 12 NC analog-to-digital converters (ADCs), digital-to-analog converters 50mV 5 11 1.6V (DACs), and RF components. 6 7 8 9 0 1 High output accuracy, remote sensing, excellent transient V V D V V performance, and soft-start capabilities also make the AP7179D ideal m m N m m 0 0 0 0 0 0 G 0 0 to power digital loads such as field-programmable gate arrays 1 2 4 8 (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.
