The RTQ2537E is a high-current (4A), low-noise (6.8μVRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 4A with an extremely low dropout (maximum 240mV). The device supports a single input supply voltage as low to 1.1V, which makes it easy to use.
The low-noise, high PSRR, and high output current capability make the RTQ2537E 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 RTQ2537E is ideal for powering digital loads such as FPGAs, DSPs, and ASICs.
The external enable control and power good indicator function make the control sequence easier. The output noise immunity is enhanced by adding an external bypass capacitor on the NR/SS pin. The device is fully specified over the temperature range of TJ = -40°C to 125°C and is offered in the VQFN-20L 3.5x3.5 package.
