RTQ2539C

3A, 6.5V, Ultra-Low Noise, Ultra-Low Dropout Linear Regulator

Features

General Description

⚫ Input Voltage Range: 1.1V to 6.5V

⚫ Output Voltage Range: 0.5 V to 5.5V

⚫ Accurate Output Voltage Accuracy (1%) Over Line,

Load and Temperature

The RTQ2539C is a high-current (3A), low-noise

(8.7V

), high accuracy (1% over line, load, and

RMS

temperature), low-dropout linear regulator (LDO)

capable of sourcing 3A with extremely low dropout (max.

180mV for RTQ2539CGQV and max. 130mV for

RTQ2539CGQWF). The device supports single input

supply voltage as low to 1.1V, which makes it easy to

use.

⚫ Ultra High PSRR: 40dB at 500kHz

⚫ Excellent Noise Immunity

⚫ Ultra Low Dropout Voltage:

The low-noise, high PSRR and high output current

capability makes the RTQ2539C ideal to power noise-

sensitive devices such as analog-to-digital converters

(ADCs), digital-to-analog converters (DACs), and RF

components. With very high accuracy, remote sensing,

and soft-start capabilities to reduce inrush current, the

RTQ2539C is ideal for powering digital loads such as

FPGAs, DSPs, and ASICs.

 180mV Max. at 3A for VQFN-20L 3.5x3.5

 130mV Max. at 3A for WQFN-12L 2.2x2.5

⚫ Enable Control

⚫ Programmable Soft-Start Output

⚫ Stable with a 47F or Larger Ceramic Output

Capacitor

⚫ Support Power-Good Indicator Function

⚫ Junction Temperature Range: −40C to 125C

The external enable control and power good indicator

function make the control sequence easier. The output

noise immunity is enhanced by adding external bypass

capacitor on the NR/SS pin. The device is fully specified

Applications

⚫ Portable Electronic Devices

⚫ Wireless Infrastructures: SerDes, FPGA, DSP

⚫ RD, IF, Components: VCO, ADC, DAC, LVDS

over the temperature range of T = −40°C to 125°C and

is offered in the WQFN-12L 2.2x2.5(FC) and VQFN-20L

3.5x3.5 packages.
