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 VIN supply voltage drops below a preset
threshold, keeping it asserted for at least 25ms after VIN has
risen above the reset threshold. An output fault detection
circuit indicates loss of regulation on LDO1. Other features
include an over current protection, thermal shutdown and
reverse battery protection.

NOTE: " Z " Suffix: Intersil Lead Free products employ special lead
free material sets; molding compounds / die attach materials and
100% matte tin plate termination finish, which is compatible with both
SnPb and lead free soldering operations. Intersil Lead Free products
are MSL classified at lead free peak reflow temperatures that meet
or exceed the lead free requirements of IPC/JEDEC J Std-020B.
Tape and Reel available. Add " - T " suffix for tape and reel packing
option. (eg. ISL6414IRZ-T for lead free tape and reel)
