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.

Key Features

  • Input Voltage Range: 1.1V to 6.5V.
  • Two Output Voltage Modes.

  • 0.5V to 2.075V (Set via PCB Layout, No External Resistor Required).
  • Accurate Output Voltage Accuracy (1%) Over Line, Load, and Temperature.
  • PSRR: 44dB at 500kHz.
  • Noise Immunity.
  • 6.8VRMS at 0.5V Output.
  • 16VRMS at 5V Output.
  • Dropout Voltage: 240mV Maximum at 4A.
  • Enable Control.
  • Programmable Soft-Start Output.
  • Stable with a 47F.
