ISL6411 - Low-Noise LDO Regulator

Features

  • ultra low noise that does not typically exceed 30µV RMS to aid VCO stability. High integration and the thin Quad Flat No-lead (QFN) package makes ISL6411 an ideal choice to power many of today’s small form factor industry standard wireless cards, such as PCMCIA, mini-PCI and Cardbus-32. The ISL6411 uses an internal PMOS transistor as the pass device. The SHDN pin controls LDO1 and LDO2 outputs whereas SHDN3.

NOT RECOMMENDED FOR NEW DESIGNS SEE ISL6414 ISL6411 Triple Output, Low-Noise LDO Regulator with Integrated Reset Circuit DATASHEET FN9081 Rev 2.00 Nov 24, 2003 The ISL6411 is an ultra low noise triple output LDO regulator with microprocessor reset circuit and is optimized for powering wireless chip sets. The IC accepts an input voltage range of 3.0V to 3.6V and provides three regulated output voltages: 1.8V (LDO1), 2.84V (LDO2), and another ultra clean 2.84V (LDO3). On chip logic provides sequencing between LDO1 and LDO2 for BBP/MAC and I/O supply voltage outputs. LDO3 features ultra low noise that does not typically exceed 30µV RMS to aid VCO stability.
