General Description

The RTQ2531A is a low-noise, high accuracy, lowdropout

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.

The RTQ2531A is designed with high PSRR and low

noise, which can meet the requirements of noisesensitive

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 TJ = ?40°C to 125°C and is offered in a WDFN-8SL

2x2 package.
