® RTQ2533W 3A, 6.5V, Ultra Low Noise, Ultra Low Dropout Linear Regulator General Description Features The RTQ2533W is a high-current (3A), low-noise (6.8μVRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 3A with extremely low dropout (max. 180mV). The device output voltage is pin-selectable (up to 3.95V) using a PCB layout without the need of external resistors, thus reducing overall component count. Designers can achieve higher output voltage with the use of external resistor divider. The device supports single input supply voltage as low to 1.1V that makes it easy to use.  The low noise, high PSRR and high output current capability makes the RTQ2533W 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 RTQ2533W is ideal for powering digital loads such as FPGAs, DSPs, and ASICs. The external enable control and power good indicator function makes 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 a VQFN-20L 3.5x3.5 package.
