RTQ2531W

500mA, 5.5V, Low Noise Low Dropout Regulator

General Description

Features

^Input Voltage Range : 1.7V to 5.5V

^Output Voltage Range : 0.6V to 5.3V

^Accurate Voltage Reference

The RTQ2531W is a low-noise, high accuracy, low-dropout

linear regulator (LDO), and is capable of sourcing 500mA.

The device supports single input supply voltage as low to

1.7V, which makes it easy to use.

^0.6V 1.5%, Over −40°C to 125°C

^Ultra High PSRR : 48dB at 500kHz

^Excellent Noise Immunity : 25μV_RMS

^Ultra Low Dropout Voltage : 150mV at 500mA

^Enable Control

The RTQ2531W is designed with high PSRR and low

noise, which can meet the requirements of noise-sensitive

applications such as RF, PLL, Clocking and analog

circuits. The regulator control circuitry includes a

programmable soft-start circuit and short circuit, reverse

current, and over-temperature protection. Other features

include an enable input and a power-OK output. The

device is fully specified over the temperature range of T_J=

−40°C to 125°C and is offered in aWDFN-8SL2x2 package.

^Short-Circuit Protection

^Output-to-Input Reverse Current Protection

^Support Power-OK Output Indicator Function

^RoHS Compliant and Halogen Free

Applications

 Portable ElectronicDevice
