RTQ2537E 4A, 6.5V, Low-Noise, Low-Dropout Linear Regulator 1 General Description The RTQ2537E is a high-current (4A), low-noise (6.8VRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 4A with an extremely low dropout (maximum 240mV). The device supports a single input supply voltage as low to 1.1V, which makes it easy to use. The low-noise, high PSRR, and high output current capability make the RTQ2537E ideal to power noisesensitive 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 RTQ2537E is ideal for powering digital loads such as FPGAs, DSPs, and ASICs.
