FN9067.1
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 30μV 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 today’s
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 I C 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.
