The RTQ2552A is a high-current, low-noise, high accuracy, low-dropout linear regulator (LDO) capable of sourcing 2A with an extremely low dropout voltage (maximum 385mV). The device supports a single input supply voltage as low as 1.1V, enhancing its ease of use.
The low-noise, high PSRR, and high output current capability make the RTQ2552A 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 RTQ2552A is suitable for powering digital loads such as FPGAs, DSPs, and ASICs.
The external enable control and power-good indicator function simplify the control sequence. 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 WDFN-10L 2.5x2.5 (FC) package.
