Triple Output, Low-Noise LDO Regulator With Integrated Reset Circuit

The ISL6412 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), 2.8V (LDO2), and another ultra-clean 2.8V (LDO3). On chip Logic provides sequencing between LDO1 and LDO2 for the BBP MAC and the I/O supply voltage outputs. LDO3 features ultra low noise that does not typically exceed 30V RMS to aid VCO stability. High integration and the thin Quad Flat No-lead (QFN) package makes the ISL6412 an ideal choice to power many of todays small form factor industry standard Wireless cards such as PCMCIA, mini-PCI and Cardbus-32.
The ISL6412 uses an internal PMOS Transistor as the pass device. The ISL6412 also integrates a reset function, which eliminates the need for the additional reset IC required in WLAN applications. The IC asserts a RESET signal whenever the VIN supply voltage drops below a preset threshold, keeping it asserted for a time set by a capacitor to GND after VIN has risen above the reset threshold. FAULT1 indicates the loss of regulation on LDO1.
