The RTQ2540H is a high-current, low-noise , high accuracy, low-dropout linear regulator (LDO) capable of sourcing 4A with extremely low dropout (max. 145mV). The device supports single input supply voltage as low to 1.1V, enhancing its ease of use.
The low-noise, high PSRR and high output current capability makes the RTQ2540H ideal for powering 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 RTQ2540H is suitable 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 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 WQFN-12L 2.2x2.5 (FC).
