RTQ2503SGQW Datasheet PDF - Richtek

●The RTQ2503S is a high-current (3A), low-noise (4.4µVRMS), 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.
