LC1761 - Dual 300mA High PSRR Linear Regulator

Description

LC1761 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current.

The output voltage for each regulator is set independently by trimming.

Features

  • Two low dropout voltage regulators.
  • 300mA output current for each LDO.
  • 25uA operating supply current per LDO.
  • Low 47uVRMS output noise.
  • Standby Mode: 0.1uA.
  • Low 160mV dropout at 300mA load.
  • 73dB PSRR at 100Hz.
  • Excellent Line regulation: 0.05%/V.
  • Independent Shutdown controls.
  • 1.2V to 3.5V Factory-Preset Output.
  • Output Current Limit.
  • Highly Accurate: ±2% (±1% customized).

LC1761 REV1.2-Revised July 2012 Dual 300mA High PSRR Linear Regulator DESCRIPTION LC1761 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at 100Hz. The LC1761 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. LC1761 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.
