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. 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<sub>J</sub> = -40°C to 125°C and is offered in a WDFN-8SL 2x2 package.
