RTQ2532N

2A, 6.5V, Ultra Low Noise, Ultra Low Dropout Linear Regulator

General Description

Features

^Input Voltage Range : 1.1V to 6.5V

The RTQ2532N is a high-current (2A), low-noise

(6.8μV_RMS), high accuracy (1% over line, load, and

temperature), low-dropout linear regulator (LDO) capable

of sourcing 2A with extremely low dropout (max. 125mV).

The device output voltage is pin-selectable (up to 3.95V)

using a PCB layout without the need of external resistors,

thus reducing overall component count. Designers can

achieve higher output voltage with the use of external

resistor divider. The device supports single input supply

voltage as low to 1.1V that makes it easy to use.

^Two Output Voltage Modes

^0.8 V to 5.5V (Set by a Resistive Divider)

^0.8 V to 3.95V (Set via PCB Layout, No External

Resistor Required)

^Accurate Output Voltage Accuracy (1%) Over Line,

Load and Temperature

^Ultra High PSRR : 40dB at 500kHz

^Excellent Noise Immunity

^^6.8μV_RMSat 0.8V Output

^^10μV_RMSat 3.3V Output

^Ultra Low Dropout Voltage : 125mV at 2A

 Enable Control

The low noise, high PSRR and high output current capability

makes the RTQ2532N 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 RTQ2532N is

ideal for powering digital loads such as FPGAs, DSPs,

andASICs.

 Programmable Soft-Start Output

 Stable with a 22μF or Larger Ceramic Output

Capacitor

 Support Power-Good Indicator Function

 RoHS Compliant and Halogen Free

The external enable control and power good indicator

function makes the control sequence easier. The output

noise immunity is enhanced by adding external bypass

capacitor on theNR/SS pin. The device is fully specified

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

offered in a VQFN-20L 3.5x3.5 package.

Applications

 Portable ElectronicDevices

 Wireless Infrastructures : SerDes, FPGA, DSP

 RF, IF Components : VCO, ADC, DAC, LVDS
