ISL6414
FN9128.1
Triple Output, Low-Noise LDO Regulator
with Integrated Reset Circuit
The ISL6414 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. High
integration and the thin Quad Flat No-lead (QFN) package
makes ISL6414 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 ISL6414 uses an internal PMOS transistor as the pass
device. The SHDN pin controls LDO1 and LDO2 outputs
whereas SHDN3 controls LDO3 output. Internal voltage
sequencing insures that LDO1 output (1.8V supply) is
always stabilized before LDO2 is turned on. When powering
down, power to the LDO2 is removed before the LDO1
output goes off. The ISL6414 also integrates RESET
function, which eliminates the need for additional RESET IC
required in WLAN applications. The IC asserts a RESET
signal whenever the V IN supply voltage drops below a preset
threshold, keeping it asserted for at least 25ms after V IN has
risen above the reset threshold. An output fault detection
circuit indicates loss of regulation on LDO1. Other features
include an overcurrent protection, thermal shutdown and
reverse battery protection.
