® RTQ2537 4A, 6.5V, Ultra Low Noise, Ultra Low Dropout Linear Regulator General Description The RTQ2537 is a high-current (4A), low-noise (6.8μVRMS), high accuracy (1% over line, load, and temperature), lowdropout linear regulator (LDO) capable of sourcing 4A with extremely low dropout (Max. 240mV). 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.
