The RTQ2531A 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.<br /><br />The RTQ2531A 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 TJ = -40°C to 125°C and is offered in a WDFN-8SL 2x2 package.
